Office 365, Email, Exchange, Outlook synchronization permission error
When using Outlook on Windows, you may receive error messages that look like the following:
In Outlook for Windows, you may receive the error "You do not have sufficient permission to perform this operation on this object, See the folder contact or your system administrator."
Synchronizer Version 15.0.4711A common cause for this is a corrupted offline Outlook Data File (.ost). The solution is to re-create this file: https://support.office.com/en-ca/article/Repair-Outlook-Data-Files-pst-and-ost-64842a0a-658a-4324-acc6-ef0a6e3567cd.

The first half of the page walks through repairing a .pst file. Skip down to the section that starts with "Re-create an offline Outlook Data File (.ost)."
Another common issue with permission of folder and synchronization is often caused by a folder or calendar that has been shared with you. The permissions are set to "Reviewer" or Limited Details and you have Outlook setup in Cached-Mode. This causes the error because it's trying to download the object without the proper permissions.
