Considerations and Limitations

This section covers considerations and known limitations of Veeam Explorer for Microsoft Exchange.


For Microsoft Outlook 2016 the preliminary releases, like Insider releases or releases provided through Monthly Channel Updates are not supported; Veeam supports only RTM/GA versions of the product. For more information. see this Microsoft article.

Considerations and Limitations Note:

Opening databases created with Exchange Server 2016 CU5 or higher on a machine running Windows 2008 might fail when using the corresponding version of the ese.dll file. To solve this, do any of the following:

  • Install Veeam Backup & Replication (either a server or console) on the machine with any Windows OS higher than Windows 2008 and run Veeam Explorer.
  • Alternatively, configure Veeam Explorer to use ese.dll version as of Exchange 2016 CU4 or earlier and obtain database files manually using file-level restore and Veeam Backup Browser.


  • Veeam Explorer for Microsoft Exchange does not support restore via PSDirect, VIX or Sphere API.
  • Sending objects that exceed 3MB in size may fail. To fix this issue, install this Microsoft update.
  • Multiple restore is not supported for public folders. Use usual (per-object) restore instead.
  • If you want to restore In-Place Hold Items or Litigation Hold Items to the original location, consider the following:
  • In-Place Hold Items restore is not supported for On-Premises Exchange Server 2013 due to EWS limitations.
  • To restore In-Place Hold Items of Exchange 2016 mailboxes, these mailboxes must have In-Place Hold enabled and applied at least once with DiscoveryHolds system folder creation. Otherwise, restore will fail with the following error:

"Failed to restore In-Place Hold Items. Restore of In-Place Hold Items into Exchange 2013 is not supported".

For information on enabling In-Place Hold and Litigation Hold, see this Microsoft article.
