Email Signatures vanishing - New Outlook
A number of people in my office had their email signatures vanish at some point overnight. We can go to sent emails and they are there, but when you go to your signature settings, nada. The signature is just gone. The signature files that old outlook looks at are still present. Which clearly tells me that new outlook doesn't look at the same files, or potentially locally at all.
Which brings me to the question. Where is the signature actually stored on new outlook? Is it a cloud thing that will continue to randomly decide to go on vacation whenever it feels like it? Or did we do something wrong to cause it to vanish.
As the "Ill pretend to know what I'm doing" IT guy. I'm baffled frankly. Our accounts are through an organization log in. And it wasn't company wide so it wouldn't be there. The old outlook signatures are still there so its not that. The best "explanation" I can come up with is that the signature is just bundled in with a bunch of temporary files and just got yeeted into oblivion for no particular reason. But even that is a complete guess based on my very limited knowledge of how windows works.
Thanks,

Fixed in our environment now! Doesn't look like the app updated (still version 1.2025.522.100), just took 2 or 3 restarts of the app for the fix to propagate.
This should be fixed - you will need to restart new Outlook to see the correct signatures dialog. (I forgot to try sending a new message to see if signatures were working before restarting outlook.)
If it's not fixed for you yet, wait a couple of hours then restart new Outlook then check again.
This morning I got lots of good reports of this being fixed. It appears to have been resolved with the very latest update Client Version: 20250523006.11
(someone who was still on Client Version: 20250523006.10 was still seeing the issue until we forced the update using the steps I have included below)
If New Outlook doesn't update on its own after a close & relaunch, you can force the update using:
Start > Run > olk.exe --force-update
**note: it's been my experience that these olk.exe commands sometimes swap between using a single dash & a double dash, so if the above throws an error that New Outlook can't do that command, try it as "olk.exe -force-update" (without the quotes) instead
Hope this helps!I experienced the same issue using the new outlook. I was able to disable the new "Roaming Signature" feature that MS included in the update. You will need to access the registry path to disable the roaming signature feature. If you GOOGLE "Disable Roaming Feature in the new outlook". The fix will come up, but I have included the registry path below.
If you're using the new Outlook, you can disable the roaming signatures feature by editing the registry.
Locate the registry key: HKEYCURRENTUSER\Software\Microsoft\Office\16.0\Outlook\Setup.
Create a new DWORD value named DisableRoamingSignaturesTemporaryToggle.
Set the value to 1.
That key is for Classic Outlook, not new Outlook. It does not work in new Outlook.
Here is the path - I tried to remove the HTML link.
Locate the registry key: HKEYCURRENTUSER\Software\Microsoft\Office\16.0\Outlook\Setup.
Create a new DWORD value named DisableRoamingSignaturesTemporaryToggle.
Set the value to 1.
I figured that was the key you found. Unfortunately, it is only for classic Outlook and does not work in new Outlook.

It's a bug. Microsoft is aware but I don't have an ETA yet. They said it was intermittent. It may be limited to users on targeted release, but I can't confirm. (I'm on targeted release.)
New Outlook stores signatures in the cloud. Classic Outlook also stores in the cloud (if you have at least one Exchange mailbox), but you can disable synced signatures. Classic can also access locally stored signatures. They will be on the Insert > signature menu or in the signature editor at the very end, under Signatures on this device, but you cannot add new ones there.
Thanks for the info... Has Microsoft officially documented this bug anywhere yet? Or are we only told if we reach out to Microsoft?
Not to my knowledge and likely won't since it was fixed. If you are still missing the signatures, restart new outlook.

Thank you for the post, Diane! Do you happen to have link to the bug report/status? I haven't been able to find an official statement from Microsoft.
All of my pre-existing signatures have been deleted and my signature settings were reset to default. Stealth nerf? This happened overnight? It was literally working less than twelve hours ago.
Honestly ... WTF? This was fine 2 days ago and now I can only have one email signature for all my accounts? Crazy!
It's a bug. It was not intentional. Don't believe everything AI says. :)
