Hi,@Glenn Maxwell
Thanks for posting your question in the Microsoft Q&A forum.
Based on your description, let's first narrow down the scope of the problem:
- Do you have Windows users in your organization? If so, do they experience the same problem?
- Are you using Blackberry Desktop or other calendar syncing software?
- Does the same problem occur if you delete and recreate the recurring meeting?
Here are my suggestions:
The sync issue can be fixed by clearing all offline items from the Calendar folder. This will remove all items from the local copy, but they can be downloaded again from the server.
