[Updated] MS Outlook signatures disappeared or missing after Office v16.63 update on Mac, issue under investigation (workaround inside)

New updates are being added at the bottom of this story…….

Original story (published on August 02, 2022) follows:

Email signatures add a nice touch and make it easier for recipients to contact you back. Your name, designation, contact number, and other details can be included in your signature.

Adding it individually to every single email you send can be a tedious task so there is a feature in MS Outlook where you can pre-save your signatures for different email addresses.

However, some MS Outlook users are facing an issue where signatures have disappeared or are completely missing after the update to Office v16.63 on Mac (1,2,3,4).

MS Outlook signatures missing after v16.63 update on Mac

After installing the update to v16.63 (2207500) on Mac, Outlook users saw their saved signatures from all email accounts disappear.

Users tried the ‘+’ button in the edit section to add new signatures but even that feature is bugged after the latest update.

I have a signature file that is attached to new emails and replies. I want to edit it, but when I go into “Settings -> Compose and Reply” there is no option for email signature. The file I have is now inaccurate, and I cannot edit it or turn it off. Any ideas on how to get the option for email signature back.

Greetings, I would like to add that I faced the same issue, reproduced the exact same steps.
Signatures disappeared;
+ button does not work;
Reverting to the legacy layout “respawns” the signatures (along with a lot of “unnamed” signatures);
Reapplying the new outlook layout shows the signatures once more;
Quitting the outlook app and restarting it makes the signatures disappear once more.

Some users upgraded to a newer build (22070801) of the same v16.63 update but it also doesn’t seem to fix this issue.

However, switching back to legacy Outlook restores the signatures, and they were also able to edit and add new signatures.

Another quick switch from legacy to the new Outlook, and all the signatures were restored. But once users restarted their Mac, again the signatures went missing.

Issue acknowledged

Fortunately, Microsoft support is already investigating this issue, but an ETA for a fix has not been revealed yet.

Potential workarounds

That said, there are potential workarounds that can help mitigate this issue for the time being.

Another one that was suggested in the Microsoft community forum was to just untick the ‘New Outlook’ button under the main file selection and it will close Outlook and restart it in the old version.
