When you try to create a new signature linked to your own account (cloud signatures), you notice that the newly created signature gets deleted after a while or you may find that the signature does not sync up with Outlook Web App (OWA).

Outlook Desktop added roaming signatures starting in Version 2303 and higher. For more information, please go to Outlook roaming signatures.


The Outlook Team is investigating this issue.  We will update this topic when we know more about root cause and possible fixes.


Account data related to Cloud Settings is cached under the Settings key. You can try working around the issue by renaming the Settings key. Support has found this step to work in some recent cases. 

  1. Open Regedit.

  2. In Regedit, navigate to path.

  3. In Regedit, right-click the Settings key, select Rename, then rename the Settings key to Settings_old.

  4. Restart Outlook.

Due to an older issue that has since been fixed, account-related data may be incorrectly cached within that registry value. The fix did not retroactively fix cases of this so its possible accounts five years or older might see it. The bug would cause any newly created signature to fail to sync to the cloud. After the (failed) sync, Outlook checks to see if the signatures that we have on the PC match the list of signatures in the roaming_signature_list. Because the new signature does not appear in the list shortly after a sync up, Outlook deletes it.
