"Proxy offline time exceeded” error after updating Veeam Backup for Microsoft Office 365 to version 4c


After updating Veeam Backup for Microsoft Office 365 4c (build backups start to fail with the “Proxy offline time exceeded”.


At the end of every month, Veeam Backup for Microsoft Office 365 collects licensing information. If your Veeam Backup for Microsoft Office 365 server is installed on a server with a time zone east of GMT (GMT +1, GMT +2, and so on) a duplicate record is mistakenly created. Because of this record, the synchronization between proxies and the controller fails and after 48 hours all remote proxies stop working.


This issue is resolved in the Cumulative Patch for Veeam Backup for Microsoft Office 365 4c which can be found here:
