Many small businesses sign up for Microsoft 365 to get professional email and the familiar Office apps, then never look further. That is understandable; you are busy running a business. But your subscription likely includes tools that could save your team time and make your data safer.
Plans differ in what they include, so check which features come with yours. Here are practical ways to get more from what you are already paying for.
Move files off individual computers
If important files live only on someone’s desktop, you are one spilled coffee or stolen laptop away from losing them. Microsoft 365 gives you better options:
- OneDrive is best for each person’s own working files. Files sync across devices and can be recovered if a computer fails.
- SharePoint is best for shared company files, such as forms, templates, client folders and policies. You can organize folders by department or project and control who has access.
Set up a simple, consistent folder structure and agree on where things belong. A little organization up front saves a lot of searching later.
Use Teams for internal communication
Microsoft Teams can reduce the flood of internal email. Create channels for departments, projects or locations so conversations stay organized and searchable. Teams also handles video meetings, screen sharing and file collaboration, so people can work on the same document instead of emailing versions back and forth.
Start small. Set up a few channels, agree on what goes in Teams versus email, and expand as your team gets comfortable.
Share calendars and mailboxes
Shared calendars make scheduling easier, especially for teams that book appointments or coordinate field work. Shared mailboxes, such as an address for support or billing, let several people see and respond to the same messages without sharing a password. That keeps customer communication from getting lost when someone is out of the office.
Turn on the security features you already have
Security settings are some of the most valuable and most overlooked parts of Microsoft 365. Start with these:
- Multi-factor authentication (MFA). MFA requires a second proof of identity beyond the password, such as an app prompt, a code or a security key. It is one of the most effective ways to protect accounts from stolen passwords.
- Individual accounts for everyone. Avoid shared logins so you can control access and remove it quickly when someone leaves.
- Careful sharing settings. Review who can share files outside your organization and how.
- Offboarding steps. When an employee leaves, block their sign-in, transfer their files and forward or convert their mailbox as needed.
Make sure your email is properly authenticated
Email authentication helps prove that messages from your domain really come from you. Since 2024, Google and Yahoo have required bulk email senders to authenticate mail with SPF, DKIM and DMARC and to offer easy one-click unsubscribe. Even if you do not send in bulk, setting up these records for your domain can help your messages reach inboxes and make it harder for criminals to impersonate you.
These settings live in your domain’s DNS records, and small mistakes can cause delivery problems, so it is worth having someone experienced set them up and test them.
Do not assume your data is backed up
Microsoft keeps its services running, but that is not the same as having your own backup of your data. Accidental deletions, ransomware or a departing employee removing files can still cause loss. A sound approach follows the 3-2-1 backup rule: keep 3 copies of your data, on 2 different types of media, with 1 copy off-site. A third-party backup for your Microsoft 365 data is worth considering.
Keep devices current too
Your cloud tools are only as safe as the computers that use them. Windows 10 reached end of support on October 14, 2025, which means no more free security updates. If any of your computers still run it, plan to upgrade or replace them. Keep Windows, Office apps and browsers updated on every device.
Setting up Microsoft 365 well takes some planning, and keeping it secure takes ongoing attention. Our managed IT services, provided through Service Your Devices, start at $300 per month and include account management, security settings, updates and support.
