Outlook for Mac provides Exchange connectivity in a Mac environment. It facilitates offline working in an Exchange environment. Synchronization between the Exchange server and client application (Outlook for Mac ) is done so that whenever there is any modification on one side (the Server-side or client-side), the change gets updated on the other side. Sometimes, this Outlook for Mac to Exchange synchronization process gets affected partially or fully due to errors, improper configurations, or OLM file corruption. Due to this, mailboxes are not updated on the server-side or the client-side, and it becomes necessary to fix Outlook for Mac not syncing with the Exchange Server.
