Outlook (Microsoft 365) Ahsay Limitations on AhsayOBM

July 21, 2025

For Outlook mail item, after using restore to original location to overwrite a mail item (the restored mail item is assigned a new mail ID), then, in the backup source tree of the same backup set:

  • the original ticked item still uses the old mail ID to reference and becomes red item.
  • there is another item (with the new mail ID) created for that mail item.

To avoid future backup error/warning, the user will need to deselect the red item and tick the mail item again (new mail ID) in the backup source tree. This re-selection of backup source is not automatically done after you restore under overwrite to original location scenario.
