Hi David,
>>But other users shared their caldendar with this specific user that is experiencing issues with their tracking on their caldendar
Does this issue only happen to one specific user? Tracking responses in his/her own calendar or the shared calendar?
According to my research, the issue may be caused by any add-ins or the meeting responses are being processed by another client, device, or third-party application. Please try starting Outlook in safe mode and see whether this issue continues. This helps
eliminate if the problem is related to any third party add-ins. To do this, please exit Outlook, press Win key + R to open the Run command, type outlook.exe /safe, press Enter.
What's more, please refer to
this official article for more details.
If you have more concern about this issue, please feel free to tell me.
Regards,
Perry
