Shared Office Calendars randomly wiped

[Justin Cohen]

How would I go about troubleshooting a set of shared calendars (Office 365 Business) that suddenly had their contents wiped.  Calendars still exist - but the contents of one calendar is suddenly empty and the contents of another have all the titles wiped and the times left behind.  No Details.

If you have a step by step troubleshooting method or can reference one for me - It would be greatly appreciated.

Hi - is anyone syncing to an iphone or android app ? I had similar symptoms more than a year ago and traced it to a user not understanding the effect of deleting shared items from their phone.

That's a great question I hadn't thought of that - Will find out. Thanks for reaching out!

Yeah, definitely check for any mobile devices involved. And enable auditing on the shared mailboxes, so you have a proper audit trail the next time this happens.
