MS Outlook signatures disappeared or missing after Office update

Hi Gabriel

Many thanks for the link.

I disabled the Roaming Signature feature in the registry key as the support page suggested and my signatures returned, along with the previous format of the signature panel.

For those also in this thread, see the instructions to follow

Hive: HKEY_CURRENT_USER

Key Path: Software\Microsoft\Office\16.0\Outlook\Setup\

Value Name: DisableRoamingSignaturesTemporaryToggle

Value Type: REG_DWORD

Value Data:1

However, toggling back to 0 brings back the the Roaming Signature panel, however none of my signatures are shown and therefore I am unable to associate them to an account. Additionally, my non MS Exh accounts do not have any associated signatures showing in the new panel. Therefore, do I assume I should raise App ticket (Help Contact Support)?

In the meantime I can continue with the Roaming feature temporarily disabled.

Many thanks, John

@john could you let me know if this worked for you?

All my signatures are gone as well. I can see them on signatures - stored on this device, but there is really no way to add them to an email.

Once again thanks for an informative webpage.

However, it only really covers formatting the layout and reading panes etc. I did however see a mention that the is "no option to Roll back to the Earlier Outlook version".

So unless there is a fix, my signatures remain unaccusable and more interestingly now any new signature created, must transmit some unhealthy link as all new mails with a new signature are returned with a Mail Delivery System error. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

Once I remove any "newly created" signature, the mail is delivered without a problem.

Hi Miguel 

Many thanks for your prompt attention. I did come across the same posting, however that is for a Mac and my issue is with a PC running Windows 11 Home build number 16.0.15726.2007.

I have 11 signatures which are no longer available to edit, or even delete so they can be replaced.

See the screenshots below:-

John,

Read over this article, Outlook roaming signatures - Microsoft Support. It explains the new roaming signatures. Your current signatures should be under Signatures on this device. You will need to create new signatures and copy those to the new ones. After this you should not have to deal with it again. Please read the full article to understand what all to expect.

If you don't see Signatures on this device then that is unexpected. If that happened please submit an In App ticket (Help Contact Support) if that is an option to investigate it further.
