Resolved Issues

General
  • Under certain conditions, applying retention on list states within SharePoint backup data stored in an object storage repository may fail with the error:
    JetError -1013, JET_errOutOfCursors, Out of table cursors.
    
  • The Veeam license cannot be revoked for a user if copies of that user’s backup data are stored in an archive-tier object storage repository.
  • The retention may incorrectly skip SharePoint websites from cleaning.
  • The Amazon Archiver Appliance may fail to start with the error:
    Incorrect parameter
    
  • Retention applied to a Microsoft Teams backup copy can mistakenly remove a corresponding group mailbox and its data if stored in the same archive-tier object storage repository.
  • Initiating new operations on a backup proxy, including creating new repositories and starting new jobs, is not possible if any of the object storage repositories associated with such a proxy are in an Out-of-Date state.
     
Backup and Backup copy
  • A Backup Copy job transfers more data than expected if the error “(412) Precondition Failed” occurs during the backup.
  • A Backup Copy job is not terminated when exceeding the configured allowed backup window.
  • Under certain conditions, a Microsoft Teams backup job targeted to a Jet-based backup repository may fail with the error:
    Failed to resolve team (ID: <team-guid>, name: <name>): Organization (ID: <org-guid>) which the team (ID: <team-guid>) belongs to not found.
    
  • Backup of an auto-expanded archive mailbox may fail with the error:
    Failed to synchronize item changes in folder: <folder-name>. Synchronization state data is corrupt or otherwise invalid.
    
  • Teams files and posts are skipped from processing during a backup copy if the previous backup copy job run has completed with the error:
    Exception of type ‘System.OutOfMemoryException’ was thrown.
    
  • The Backup Copy job displays the incorrect item count if a new version of a backed-up file has been added in the production environment between the next backup and the backup copy job runs.
  • A Backup Copy job containing Teams objects fails with the error:
    An item with the same key has already been added if those teams are using the same SharePoint site.
    
  • Under certain conditions, in hybrid organizations, the backup of a security group may fail with the error:
    Cannot process argument transformation on parameter ‘Identity’. Cannot convert value "00000000-0000-0000-0000-000000000000".

  • A Backup Copy job skips files from a SharePoint site if the processing of those files failed on the previous job run.
     
Restore

  • In the session history, a restore session initiated via PowerShell and started for a specific retrieved SharePoint, OneDrive, or Microsoft Teams item is incorrectly displayed with the ‘Entire organization’ flag.
  • When browsing a backup stored in object storage, Veeam Explorer for Microsoft Teams may not display the reply to a post that has been deleted in the production environment.
  • Veeam Explorer for Microsoft Teams doesn’t display @mentions added to team posts backed up via Teams Export APIs.
  • The ‘Modified by’ field of a SharePoint item is changed after restore, if this item was restored from a backed-up list created using a certain template.
  • Restoring a team that has been created via PowerShell with the HiddenGroupMembershipEnabled parameter set to ‘true’, fails with the error:
    Visibility of a group with hidden membership cannot be updated.
    

PowerShell
  • The Set-VBOEmailSettings cmdlet does not support the configuration of connecting using SSL without authentication.
     
REST API

    Note: Depending on the job configuration, the job may complete with a Success status, and the problem may occur unseen
