Lightning Sync with Outlook

Good Morning, I recently (past few days) am having issues with our calendar events from Salesforce not hitting the outlook calendar.

I have confirmed nothing has changed on our Microsoft Exchange side.

I have tested with multiple users including myself.

I do not have Einstein Activity turned on but I hadn't before this with no issue.

I'm wondering if it has something to do with the winter release.

Any recommendations are greatly appreciated.

Thanks and Happy Friday!

Kim
