Veeam have snuck this update out late in the day!
Veeam Backup for Office 365 5c has been released! Full notes here
In addition to the key Teams bug fix that has been doing the rounds as a hotfix there seem to be mainly other Teams related fixes such as inability to backup chat messages newer than October 2020 and Backup Proxies out of memory when backing up to object storage!
Time to get patching!
Thanks
