There are a lot of issues that have been resolved in version 5c build 22.214.171.124 of Veeam Backup for Microsoft Office 365:
Under certain conditions a proxy may fail with an Out of Memory error during backup to an object storage repository.
Microsoft Teams backup may fail with a Folder processing failed: Team Chat. Restriction contained too many elements error.
Backup of Team Chat messages created after October 2020 may fail with a Failed to get TeamsMessagesData folder error.
Microsoft Teams backup fails with an Object reference not set to an instance of an object error.
OneDrive backup fails with an Object reference not set to an instance of an object error if there’re any large OneNote files that are open and being edited during backup.
In Backup-as-a-Service (BaaS) scenarios, exporting backup data to a local disk on the tenant side fails with a timeout error.
Export operations in Veeam Explorer for Microsoft Exchange may fail with a Connection to server was unexpectedly closed error.
For larger Office 365 organizations, some OneDrive accounts may not be displayed in the Copy OneDrive wizard.
The SharePoint site title field is empty if such a site has been added to a backup job explicitly via the REST API and the site title has not been explicitly specified.
Removing a group with audit items via the REST API doesn't work as expected but reports back response code 200.
In Backup-as-a-Service (BaaS) scenarios with the modern app-only approach, obtaining a token for tenant authentication via the REST API fails if a combination of capital and lower-case letters is used to specify the client_id parameter.
