TL;DR Several Microsoft 365 Features, when setup and administered by experienced experts, can accelerate growth in a predictable, manageable way.
Picture a Nashville medical practice that grew from two clinics to four in under three years. It started with the original Midtown office, then added Franklin, Murfreesboro, and Hendersonville. Headcount climbed from about 60 people to 140, but the front desk still ran on the habits of the first clinic.
Staff schedules lived in a spreadsheet the practice administrator emailed every Friday. Shift swaps happened in a group text nobody could search. When a patient left a voicemail, a medical assistant often called back from her own cell phone because the clinic line was tied up.
Patients saved that number. When she left the practice, the number left with her, along with months of patient call history on a phone the practice never controlled.
Nobody made a bad decision here. The practice’s systems were built for a company of 40 people, and that company no longer existed.
Here is the part most leaders miss: the practice already paid for most of the fix. Its Microsoft 365 subscription included scheduling, device management, and security tools nobody had switched on. Some Microsoft 365 features are optional at 40 people and required at 120. This guide covers which ones matter, what they cost after Microsoft’s 2026 pricing changes, and what to turn on first.
What Microsoft 365 Features Does a Growing Business Already Pay For?
Most growing businesses run one of three Microsoft 365 Business plans: Basic, Standard, or Premium. All three include business email, Teams, and cloud file storage. As of July 1, 2026, Microsoft lists Basic at $7 per user per month, Standard at $14, and Premium at $22, according to Microsoft’s licensing update.
The difference between the plans sits underneath the apps your team sees every day. Premium adds the tools that manage devices, control who signs in from where, and protect email and files. Those are the features that start to matter once you pass 50 people.
| Plan | List price per user per month (July 2026) | What it adds | Best fit |
|---|---|---|---|
| Business Basic | $7 | Email, Teams, OneDrive, SharePoint, web and mobile Office apps | Teams that work mostly in a browser |
| Business Standard | $14 | Everything in Basic, plus desktop Word, Excel, PowerPoint, and Outlook, plus Microsoft Bookings | Office-based teams with simple security needs |
| Business Premium | $22 | Everything in Standard, plus Intune device management, Entra ID sign-in policies, Defender for Business, and Defender for Office 365 | Businesses hiring regularly, running more than one location, or handling sensitive data |
Two details matter for a company your size. First, the Business plans are built for organizations up to 300 users, so a 50 to 250 person company fits inside them without jumping to Enterprise pricing. Second, Premium’s price did not change in July, while Basic and Standard went up. For many growing companies, the gap between Standard and Premium is now $8 per user per month.
What Teams Phone Costs on Top of Your Plan
Calling outside phone numbers from Teams is not part of any Business plan. Teams Phone is an add-on. Teams Phone Standard runs $10 per user per month, and Teams Phone with a domestic Calling Plan runs $17.
That add-on is what gives an employee a real business phone number inside the Teams app on their desk and on their phone. It also includes the call routing a multi-location business needs: a main number per location that rings whoever is on shift, plus voicemail that stays with the business.
You do not have to license every employee for it. In the Nashville practice scenario, only the front desk staff and medical assistants who call patients need a number. Clinical and back-office staff keep calling each other inside Teams at no added cost.
Which Microsoft 365 Features Matter Most When You Hire Every Month?
Four features decide whether a new hire is productive on day one: Windows Autopilot, group-based access, shared mailboxes, and Shifts. At 40 people, someone in the office can set up a laptop by hand and add a new hire to the right folders. At 120 people, hiring every few weeks across several locations, that manual work turns into a part-time job nobody was hired to do.
Laptops That Set Themselves Up
Windows Autopilot and Microsoft Intune, both part of Business Premium, let a new laptop ship straight from the supplier to the employee’s home or clinic. The employee signs in with their work account. Company apps, settings, and security policies install on their own.
The practical result: no one in the office spends a morning unboxing devices, and every laptop starts with the same protections. For a practice opening a fourth location, that means a new clinic’s devices arrive ready instead of waiting on someone to drive over from Midtown.
Access Based on Role, Not on Memory
Microsoft Entra ID, included in Business Premium, lets you assign access to groups instead of individuals. Create a group called Franklin Front Desk once. Connect it to the right Teams channels, SharePoint sites, licenses, and shared mailboxes.
Add a new hire to that group and everything follows. Remove them and everything goes away. The difference at 150 people is large: access stops depending on whether someone remembered every folder the last front desk hire had.
Shared Mailboxes for Shared Work
Addresses like scheduling@, billing@, or careers@ belong in shared mailboxes, not in one person’s inbox. A shared mailbox lets several employees read and reply from the same address. Shared mailboxes under 50GB do not need their own license, so they cost nothing extra.
When the billing coordinator goes on vacation or leaves, the mail keeps flowing and the history stays with the business.
Shifts for Schedules That Change Every Week
Shifts is a scheduling app built into Teams. Managers publish schedules, employees see their shifts on their phones, and swap or time-off requests go to a manager for approval in the same app.
In the Nashville practice scenario, Shifts replaced the Friday spreadsheet and the group text. A medical assistant in Hendersonville who needs Thursday off requests a swap from her phone. Her manager approves it from Franklin. Everyone sees the updated schedule without a single email.
One boundary worth stating clearly: Shifts handles staff schedules. Patient appointments stay in the practice’s existing scheduling system. The two serve different jobs, and mixing them creates confusion.
Our onboarding playbook treats day one as the test. If a new hire waits on a login, a laptop, or a folder, a step was missed upstream, and the fix belongs in the process rather than the person.

What Are the Best Ways to Use Microsoft Teams at 150 People?
The best ways to use Microsoft Teams at 150 people come down to structure. Every team needs an owner, names follow one pattern, work decisions live in channels, and finished projects get archived. Without those habits, Teams fills up with duplicate groups, and new hires can’t tell which one is real.
At 40 people, Teams grows on its own and everyone knows where things are. At 150, that same freedom produces three teams called Front Desk, a channel nobody has posted in since spring, and files that only one person can find.
Four Rules That Keep Teams Usable
- Give every team two owners. One owner leaves eventually. Two owners means someone can always add members, change settings, and clean up.
- Use one naming pattern. Location first, then department: Franklin Front Desk, Murfreesboro Clinical, Company Leadership. A new hire can guess the right team without asking.
- Put decisions in channels and quick questions in chat. Channel posts are visible to the whole team and searchable later. A decision made in a private chat between two people is invisible to the third person who needs it.
- Archive teams when the work ends. A project team for a new clinic opening should be archived once the clinic opens. Archiving keeps the history and removes the clutter.
Teams Phone Keeps Calls With the Business
For businesses that talk to customers or patients by phone, Teams Phone is the feature that changes daily work the most. Each patient-facing employee gets a business number inside the Teams mobile app. When they call a patient back from the parking lot or another clinic, the patient sees the practice’s number, not a personal cell.
In the Nashville practice scenario, this solved the problem that started the whole project. Callbacks now come from the clinic. Voicemails land in Teams, where the next person on shift can see them. When an employee leaves, their business number and call history stay with the practice.
Each location’s main number can also route to whoever is on shift at that clinic. A patient calling the Murfreesboro office reaches Murfreesboro staff, even when the person who usually answers is out.

Where Should Company Files Live: OneDrive, SharePoint, or Teams?
Personal drafts belong in OneDrive. Anything the business needs after an employee leaves belongs in SharePoint. Files shared in a Teams channel already live in SharePoint behind the scenes, so Teams and SharePoint are two doors into the same room.
Most growing companies get this backward without meaning to. A spreadsheet starts as one person’s draft, gets shared with a few coworkers, and two years later the whole front desk depends on a file that lives in a single employee’s OneDrive.
| Where | What belongs there | Who can see it | What happens when the owner leaves |
|---|---|---|---|
| OneDrive | Personal drafts and work in progress | The owner, plus anyone they share with | By default, Microsoft keeps it for 30 days after the account is deleted, then it is gone |
| SharePoint | Company records, policies, templates, shared reference files | Whoever the site’s group allows | Stays with the business |
| Teams channel files | Working files for a team or project | Every member of that team | Stays with the business, stored in SharePoint |
The Rule That Prevents the Problem
A simple test works for most companies: if two or more people need a file to do their jobs, it moves out of OneDrive. It goes to the team’s channel or to a SharePoint site.
That one rule prevents the most common file problem we see when a growing business changes technology partners. Important documents turn out to live in the accounts of people who left months ago. Recovering them is sometimes possible and always slower than putting them in the right place from the start.
For the Nashville practice scenario, the clinic procedures binder, the new hire checklist, and the location contact sheet moved into one SharePoint site per clinic. Staff open them from a tab in their clinic’s Teams channel, so nobody has to remember where SharePoint is.
Which Microsoft 365 Security Features Protect You as Headcount Grows?
Five security features carry the most weight for a 50 to 250 person company: multifactor sign-in, sign-in policies, email and link scanning, device protection, and app protection for personal phones. Business Premium includes all five. Every new employee is another inbox, another password, and another phone, so these features matter more with each hire.
Multifactor Sign-In and Sign-In Policies
Multifactor sign-in asks for a second proof, usually a tap in the Microsoft Authenticator app, before anyone gets into a work account. It is the single most effective step against stolen passwords.
Sign-in policies, called Conditional Access in Microsoft’s terms, go further. They set rules about who can sign in, from where, and on what device. A common starting point: block sign-ins from outside the United States, and require a managed device to open patient or financial data. A stolen password used from overseas then gets nothing.
Email and Link Scanning
Microsoft Defender for Office 365, included in Business Premium, checks links when someone clicks them, not only when the email arrives. It also opens attachments in a safe space before they reach the inbox. Phishing emails often carry links that look harmless at delivery and turn malicious hours later, so the click-time check matters.
As part of the 2026 update, Microsoft added this click-time link protection to Business Basic and Standard as well.
Device Protection
Microsoft Defender for Business watches laptops and desktops for signs of attack and can isolate a device that is compromised. Paired with Intune, it gives you one place to confirm every company device is encrypted, updated, and protected.
App Protection for Personal Phones
Many growing businesses let employees use their own phones for work. Intune app protection, part of Business Premium, keeps work data inside approved apps like Teams and Outlook on those phones. Staff cannot copy patient details from Teams into a personal notes app or text thread.
In the Nashville practice scenario, this is what made Teams Phone on personal devices workable. The practice controls its data on the phone without managing the phone itself. Nobody’s personal photos or texts are visible to the practice, and nobody has to carry a second device.
Offboarding in One Step
When someone leaves, the account is disabled, active sessions end, and work data is removed from their phone. The practice’s number and call history stay behind. Before, offboarding meant hoping a former employee deleted patient voicemails from a personal phone. After, it is a checklist item that takes minutes.
If you work in healthcare, one more step belongs on the list. Confirm that your agreement with Microsoft covers the services your staff use for patient communication, including Teams Phone voicemail and any call recordings, and that those services are set up to match your privacy obligations.
What Changed in Microsoft 365 in 2026?
The biggest Microsoft 365 updates of 2026 took effect on July 1. Prices rose for Business Basic and Business Standard, Business Premium held steady, and every Business plan gained more mailbox space and expanded Copilot Chat features. Existing customers keep their current price until their first renewal after July 1, per Microsoft’s licensing update.
| Plan | Before July 1, 2026 | After July 1, 2026 | Added in 2026 |
|---|---|---|---|
| Business Basic | $6.00 | $7.00 | 50GB more email storage, click-time link protection, Copilot Chat enhancements, Copilot Chat Analytics |
| Business Standard | $12.50 | $14.00 | 50GB more email storage, click-time link protection, Copilot Chat enhancements, Copilot Chat Analytics |
| Business Premium | $22.00 | $22.00 | 50GB more email storage, Copilot Chat enhancements, Copilot Chat Analytics |
Prices are list prices per user per month. Microsoft finished rolling out the new features by August 1, 2026.
What Copilot Chat Now Does
Copilot Chat is the AI assistant included with Microsoft 365 at no extra cost. Microsoft’s 2026 update gave it awareness of your inbox and calendar, plus access to agents inside Word, Excel, and PowerPoint. Copilot Chat Analytics shows administrators how much the team actually uses it.
The full Microsoft 365 Copilot, which works across all of your company’s files, emails, and meetings, is still a paid upgrade. Microsoft made two bundles permanent this year: Business Standard with Copilot at $23.50 per user per month and Business Premium with Copilot at $32. Standalone Copilot Business rose from $18 to $21.
What This Means for Your 2027 Budget
If you renewed before July 1, the new price arrives at your next renewal. For a 120-person company on Business Standard, the increase adds $180 a month, or $2,160 a year. The same company moving to Business Premium pays $960 more per month than it would on Standard at the new price, and gains device management, sign-in policies, and security tools it would otherwise buy separately.
Whether full Copilot belongs in that budget is a separate question, and the answer depends more on your processes than on the license. We cover that decision in our post on AI strategy for growing businesses.
Giving Employees AI Is Not an AI Strategy
When Does Microsoft 365 Need a Dedicated Technology Partner?
Microsoft 365 needs a dedicated partner when the features you pay for stop getting used because nobody owns them. That usually shows up between 50 and 150 people, when the person who set up Microsoft 365 is also running operations, payroll, or a clinic.
A few signs you have reached that point:
- You hire every month, and each new hire’s first day depends on one person remembering every step.
- You run more than one location, and each one has set up Teams, files, and phones its own way.
- Nobody has reviewed your licenses since the last renewal, so you are paying for accounts that belong to people who left.
- You pay for Business Premium and use it like Business Basic.
If two or more of those sound familiar, ask yourself the question we ask every growing business: have you outgrown your IT provider?
What a Partner Should Handle
When companies search for Microsoft 365 managed services, they are usually looking for someone to own the setup and keep it current as the business grows. In practice, that means configuring the features in this guide, reviewing licenses before each renewal, onboarding and offboarding staff the same way every time, and tracking Microsoft’s changes so you hear about them before they show up on an invoice.
At Stringfellow Technology Group, that work is ProSafeIT, our service for growing businesses across the Southeast. For healthcare organizations, HealthSafeIT applies the same approach with healthcare’s privacy requirements and patient communication in mind, like the Teams Phone and Shifts setup in the Nashville practice scenario. STG holds the Microsoft Solutions Partner designation for Modern Work, which covers the Microsoft 365 tools in this guide.
The practice in our scenario did not need new software. It needed someone to switch on what it already owned, set it up for four clinics instead of one, and keep it that way as the next location opens.
If your Microsoft 365 setup was built for a smaller version of your company, we can walk through what you already pay for and what to turn on first.
