How to fix the syncing of Teams and outlook calendars

Question

If I create any meetings in Teams it is not being reflected in Outlook calendar

Answer 1

Hello,

What type of email address do you use for your Microsoft account? If you use a third party email address instead of Microsofts native domain one (native one is outlook.com, or hotmail.com), then your meetings created in Teams will only stay in Teams calendar.

Answer 2

To fix the syncing issue between Teams and Outlook calendars, you can try the following steps:

1. Check ActiveSync Relationship: If you're using a mobile device, ensure that the ActiveSync relationship is properly set up. If there are issues, you may need to remove and recreate the ActiveSync relationship on your device.
2. Recreate the ActiveSync Relationship: On your mobile device, remove the ActiveSync relationship and then re-establish it. You can do this by going to the settings in Outlook Web App and deleting the existing ActiveSync relationship.
3. Disable Outlook Add-ins: Sometimes, third-party add-ins can interfere with calendar syncing. Disable any Outlook add-ins that might be affecting calendar items and check if the issue persists.
4. Check Calendar Settings: Ensure that your calendar settings in both Teams and Outlook are configured correctly. This includes checking for any discrepancies in working hours and meeting settings.
5. Update Software: Make sure that both Teams and Outlook are updated to the latest versions, as updates often include bug fixes and improvements.
6. Clear Cache: If you are using the desktop version of Outlook, clearing the cache may help resolve syncing issues. You can do this by closing Outlook, navigating to the cache folder, and deleting the contents.

If these steps do not resolve the issue, consider reaching out to Microsoft Support for further assistance.
