Outlook Calendar on Mac Sync Issues with Apple calendar app

I have been having issues with syncing events between my Outlook calendar on Mac and my Apple calendar application (on my MacBook Pro) for the last couple of months. Before then, the syncing worked like a charm.

I've had many calls with the Apple support team and they got it working every single time but it stops syncing again after a few hours or at most a day.

Do you have any tips on what I may need to do to resolve this issue from the Outlook side of things?

An interesting fact is that my iPhone and my Outlook calendars are syncing perfectly fine. It's just the connection between my MacBook Pro and Outlook that doesn't work

I would so very much appreciate your insights and guidance.

Thank you!

    Finally solved this with the help of my IT department (they are amazing). Here's what they told me to do:

    You need to update the desktop app on the computer. Running 16.55. It is at 16.65 now. Go to Macintosh HD > Library > Application Support > Microsoft > MAU2.0 > Microsoft Auto Update.app

    That explains why it stops working occasionally.

    I have the same problem. Syncing is inconsistent. Seems to come and go. Particularly problematic since Outlook Mac Calendar is so graphically horrible displaying calendar items, especially in a (scrolling) monthly view, compared with Mac Calendar. It's fine as a scrolling side bar to Outlook Mail, and would be more so if it scrolled past 7 days!

    I have tried restarting Sync Services and the Terminal commands without success. Outlook is syncing perfectly with my iPhone on recent IOS, but will not sync with my Mac Calendar app. MacBook Pro Big Sur 11.6.7. Suggestions welcome.

    this seemed to work for me (for now), found on https://www.nucleustechnologies.com/blog/fixed-outlook-for-mac-not-syncing-with-exchange-server/:

    1. Restart the Sync Services Agent Restarting the Sync Services Agent is one of the best ways to fix the Outlook for Mac not syncing with the Exchange Server issue. Follow the steps below to get through this process easily.
      1. Shut down Outlook for Mac.
      2. Now go to Applications and tap on Utilities.
      3. Next, select the option Activity Monitor.
      4. Go to the tab Process Name & tap on Sync Services Agent.
      5. Choose the process and tap on the Quit option.
      6. Lastly, exit the Activity Monitor & access your Outlook for Mac application once again to check whether this issue is fixed or not.

    This solution works for me, but from what I've read it will stop syncing again after a few hours or days. This is a problem that seems to have been ongoing for many months. I just switched from Google to O365 and never had problems with Google calendar or Apple calendar, but am seeing this issue immediately with O365 calendar. Is this an MS bug or an Apple bug? Has anyone reported the issue formally to either?
