This week, we saw the release of version 5d of Veeam Backup for Microsoft Office 365. Version 5d with build number 5.0.3.1033 provides support for Veeam Backup and Replication 11a. However, it doesn't offer compatibility with Windows Server 2022.

What's New

Veeam Backup for Microsoft Office 5d offers support for installations on top of Veeam Backup & Replication 11a.

What's Fixed

Backup

• A retry is not initiated for OneNote and Excel files that have been changed during backup and failed to be processed with the following warning:

The remote server returned an error: (409) Conflict

• Under certain conditions, in hybrid organizations, adding some users to a backup job fails with the following error:

An item with the same key has already been added

Restore

• In Veeam Explorer for Microsoft Teams, restore of a single team tab may fail with the following error:

Object reference not set to an instance of an object

• Under certain conditions, in Veeam Explorer for Microsoft Exchange, mounting a standalone Veeam Backup for Microsoft Office 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 following error:

Post Not Found

• Saving a SharePoint file as a ZIP archive via REST APIs fails with the following error, if the length of the file path including the file name exceeds 255 characters:

Could not find a part of the path

• 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.

Upgrading to version 5d

If you're running a previous version of Veeam Backup for Microsoft Office 365, you can simply upgrade to version 5d from versions 3.0 (build 3.0.0.422) and upwards. However, upgrades from the beta version of Veeam Backup for Microsoft Office 365 version 5 are not supported.

After upgrading, your installation's build number changes to 5.0.3.1033.
