Microsoft 365 Review

What Microsoft 365 does

Microsoft 365 (formerly Office 365) is Microsoft's bundled productivity suite — Outlook for email, Teams for messaging and video, OneDrive and SharePoint for file storage, and the Office desktop apps (Word, Excel, PowerPoint, Outlook). For ABA agencies, it serves the same role as Google Workspace: the underlying email-and-document backbone that everything else sits on top of.

The product has been HIPAA-eligible since the early 2010s. A Business Associate Agreement is available across most Business and Enterprise plans through the Microsoft Service Trust portal, with broad service coverage that includes Exchange Online, Teams, OneDrive, and SharePoint.

Who it's for

Microsoft 365's clearest fit is the mid-size ABA agency (20+ employees) that's already running on Office desktop apps and prefers Outlook over Gmail. The integration between desktop Office, OneDrive, and Outlook is meaningfully tighter than the Google equivalent for users who live in Word and Excel.

It's also a natural choice for agencies that want a unified messaging-plus-video tool. Microsoft Teams is included on most Business plans and replaces a separate Zoom + Slack pairing for many operations. Larger agencies with formal IT staff often default to 365 for its admin depth and policy controls.

It's less ideal for solo BCBAs and small clinics who don't already have Office in their workflow. The setup and admin complexity is higher than Workspace, and many of 365's bundled features go unused at that scale.

What stands out

Office app fidelity is the single biggest practical advantage. Word documents, Excel spreadsheets, and PowerPoint files render and edit correctly in 365 in a way that Google Docs equivalents still don't quite match. For agencies sending formal documents to school districts, payers, or partners — where formatting matters — Office desktop apps remain the gold standard.

Teams is the second standout. Bundled with most Business plans, it combines persistent team chat, video meetings, file sharing, and integration with Office in one app. For agencies already paying for Zoom + Slack separately, switching to 365 + Teams often nets a real cost reduction.

Exchange-grade email is the third advantage. The mature spam filtering, retention policies, eDiscovery features, and audit logging matter for agencies with legal or compliance scrutiny. Workspace has caught up over time but still trails on enterprise-grade email administration.

Where it falls short

Setup complexity is the most consistent operator complaint. License assignment, group policy configuration, security baseline setup, and tenant administration require meaningful IT time investment. Small clinics without internal IT often hit walls during initial deployment and end up calling external Microsoft consultants.

License management gets messy as agencies grow. Power BI, Visio, Project, and other Microsoft tools have separate licensing structures that overlap and confuse — operators routinely pay for licenses that nobody uses.

Pricing scales similarly to Workspace, and many of the bundled features at higher tiers (Power Automate, advanced compliance, Power BI) are wasted at small-clinic scale. Operators often pay Business Premium prices for value they don't extract.

Teams adoption can also stall. Agencies that turn on Teams without clear playbooks for what goes there vs. email vs. existing Slack end up running multiple messaging tools with none getting real adoption.

Pricing

Microsoft 365 Business Basic starts at $6/user/month (web and mobile Office apps); Business Standard at $12.50/user/month adds desktop Office apps; Business Premium at $22/user/month adds advanced security and device management. HIPAA-eligible plans are available across the Business and Enterprise tiers with the BAA accepted through the Service Trust portal.
