Microsoft has confirmed it will retire the classic version of Microsoft Teams on the 1st of July 2025. For businesses still using the original desktop client, this means a final transition to the new Teams experience is now essential.
For Dr Logic clients, there’s no need to worry – if we manage your Teams environment, we’ve already got you covered. But here’s what’s happening, why it matters, and what steps (if any) are needed.
What’s Changing?
The classic version of Teams – sometimes referred to as “Teams 1.0” – has been in use since the platform launched. It has served many organisations well, but it’s time to move on.
Microsoft is officially ending support and access to the legacy desktop app, which means:
- No further updates or security patches
- No compatibility fixes for new systems or integrations
- Automatic prompts directing users to the new Teams app
Access to Teams will continue through the updated desktop version or via supported web browsers. The change only affects desktop installations of the classic app on Windows and macOS.
Why the Switch?
The new version of Teams – already available and widely adopted – offers a better, faster, and more efficient experience. Key improvements include:
- Performance: Launches twice as fast, uses less memory and CPU
- User Interface: Cleaner design, easier navigation, and more consistent with other Microsoft 365 tools
- New Features: Enhanced meeting tools, better search, support for multiple accounts, and AI integration such as Copilot
- Security and Support: Continued updates, patches, and stronger defences against evolving threats
Microsoft is effectively unifying the Teams experience across platforms, which reduces complexity for users and IT admins alike.
What This Means for SMBs
For small and medium-sized businesses, the implications depend on how Teams is currently managed.
If your setup is looked after by Dr Logic, you’re likely already using the new version – or we’ll be handling the upgrade for you behind the scenes.
If you’re managing Teams independently or aren’t sure which version your staff are using, now is the time to check. Remaining on classic Teams after July could lead to:
- Loss of access or reduced functionality
- Compatibility issues with other Microsoft 365 tools
- Frustration from users unfamiliar with changes
- Potential security gaps from unsupported software
Your Action Checklist
- Confirm Which Version You’re Using
Look for “New Teams” toggles in your app or contact your IT provider to confirm the current setup. - Upgrade Where Needed
The new client can be installed manually or pushed via centralised device management tools. Systems need to be running Windows 10 version 19041+ or macOS 11+. - Inform and Support Staff
The interface is familiar, but a short internal update or walkthrough can ease the switch. Highlight any new tools or changes to avoid confusion. - Review Integrations
If your Teams setup connects with third-party apps or services (e.g., CRMs, VoIP, file sharing), test compatibility to ensure everything continues to work smoothly.
