- Office 365 Connectors Retirement from Microsoft Teams: Owners of webhook-based Office 365 connectors in Teams must update their URLs to a new structure by January 31, 2025 to avoid service disruptions; all webhook-based connectors must be updated to continue posting messages in Teams. Microsoft recommends migrating webhooks to the Teams Workflow app.

- Starting in late January 2025, any OneDrive accounts left unlicensed for more than 90 days will be automatically archived, hitting customers with extra costs to regain access in Microsoft Archive. They will be charged $0.05 per GB per month to store unlicensed OneDrive content and $0.60 per GB to reactivate the account in the Microsoft 365 archive. Microsoft recommends either deleting these accounts or assigning them a license.
- Starting next month, the blog said, “Microsoft will remove the ‘Monitor’ action in the Safe Attachments policy. Any existing policies set to ‘Monitor’ will be automatically changed to ‘Block.’ The recipients, status, or priority configured in the policy will remain unchanged.”
These moves followed the deprecation of the legacy Teams client in March 2024 (with its end of availability scheduled for July 1, 2025), which Roberts said “had more to do with efficiency than with aesthetics. They’ve moved off of Electron and AngularJS [development platforms] to WebView2 and React. This is meant to improve performance, responsiveness, and optimization. Basically, this is Microsoft cleaning up its technical debt.”
That is, he said, “one of the benefits of a SaaS environment, and while it might be a bit of a pain for users to make the transition, the old and new Teams are similar enough that the change management exercise shouldn’t be overwhelming. They have to cut over at some point; otherwise, they’re left maintaining a fractured environment, which is ultimately not really beneficial to anyone in the long term.”
The march to the cloud, said Roberts, “continues with the end of support for M365 Apps support on Windows Server 2016/2019 and the end of support for the legacy Office 2016 and 2019 products [which takes effect in October of this year]. I don’t think anyone is surprised that they would make this choice. Microsoft loves recurring revenue. I imagine most corporate clients are already M365 customers, but for those who are holding out, this could complicate things from a security and feature perspective.”
