Connecting and synchronizing calendars across Microsoft Teams and other services like Outlook
Dear @Melinda Cape, Ms,
Thank you for posting your question in the Microsoft Q&A forum.
To be honest, as a moderator, I share the same experience as other users and do not have the specific tools to investigate this issue. Only the Microsoft Technical Team has the necessary tools to perform such a deep-dive investigation. However, I can provide the guidance you need to reach out to them, as they are the ones who can actually deploy a fix.
Based on my understanding, you are looking for a "Disable" toggle or a setting to stop the Bookings app in Teams from connecting to or overwriting data on the Web version. Typically, synchronization is meant to update the latest information across devices. But in this case, instead of updating, Teams is incorrectly removing (overwriting with null values) the staff color categories you have assigned. Currently, Microsoft does not provide a configuration option or toggle in the Admin Center to separately disable synchronization between Teams and Web. The Bookings app in Teams acts as a wrapper that connects directly to server data; therefore, every time the app is opened, it automatically triggers a data check and update process. Since this is causing data loss, it is considered abnormal behavior that requires the Microsoft Technical Team to investigate, especially as everything is currently functioning normally in my own test environment.
In terms of Product Design, Microsoft intended the Bookings apps on Teams and Web to be two interfaces of the same database. All staff settings, including category colors, should be displayed with consistency to ensure an uninterrupted user experience. Color-coding for staff is not a premium or unique feature exclusive to the Web; it is a standard part of Staff Metadata. Therefore, Teams failing to display or actively deleting this data is a deviation from the standard design and must be investigated.
Because this is abnormal behavior occurring within your specific tenant, and as you mentioned, it was working correctly previously, data preservation must be the top priority. To get a specific fix roadmap for this issue, please help me reach out to your Global Admin and ask them to submit a support ticket via the Admin Center.
