Backup A retry is not initiated for OneNote and Excel files that have been changed during backup and failed to be processed with “The remote server returned an error: (409) Conflict” warning. Under certain conditions, in hybrid organizations, adding some users to a backup job fails with the “An item with the same key has already been added” error. Restore In Veeam Explorer for Microsoft Teams, restore of a single team tab may fail with the “Object reference not set to an instance of an object” error. Under certain conditions, in Veeam Explorer for Microsoft Exchange, mounting a standalone Veeam Backup for Microsoft 365 repository database restored from a Veeam Backup & Replication backup may fail. RESTful API Under certain conditions, the (GET) /v5/RestoreSessions/{restoreSessionId}/organization/teams/{teamId}/posts/{postId} request fails with the “Post Not Found” error. Saving a SharePoint file as a ZIP archive via REST APIs fails with the “Could not find a part of the path” error, if the length of the file path including the file name exceeds 255 characters. If the Microsoft Teams service is enabled for an organization, no data for such an organization can be requested with the REST API calls earlier than v5. Restoring and saving Teams files with the (POST) /v5/RestoreSessions/{restoreSessionId}/organization/teams/{teamId}/files/{fileId}/action request completes with code 500, although the files are restored successfully. A title of a SharePoint site added to a backup job via REST APIs is empty if such a title has not been explicitly specified.
