Sync Error when connected to Office 365


I am getting the below error when I am syncing the Office 365 account.

[Exchange Web Services]Set action is invalid for property.

From Logs:
18:27:55 [email protected] [Exchange Web Services] MailClient.Storage.Application.ItemOperationException: Set action is invalid for property.
GUIStatus_Exception_Reported = True

Did anyone face this?


I have the same issue too

Normally this is an error on a calendar.

Go to the Calendar section and right-click on that calendar folder. Choose Properties > Repair > Repair.

If there are many calendar folders you will need to do it for each one.
