Roaming Signatures in OWA already done and EWS is not longer possible - No MS Graph API exist

Question

Hello,

in Outlook Web App is already the Roaming Signatures implemented, wich disable the old EWS way.
Outlook currently not Support this Feature and the Roadmap is again moved now from July 2022 to September 2022.
See: https://www.microsoft.com/de-de/microsoft-365/roadmap?filters=&searchterms=60371

There is not API available currently wich Support official Roaming Signatures.
The Feature was planed at first for late 2020. Is hard to plan new Features if they are permanently moved.

Questions:

1. Is there a was to disable the New Feature in OWA to use the "old" way by EWS? (In Outlook is a registry TOGGLE possible)
2. Is there a Plan, when MS Graph will support this Feature?
3. Microsoft currently bring new Features without any API. What is the Reason?

Best Regards
Manfred

Answer 1

This half baked feature is really frustrating. We auto generate signatures based on role in the company, pulling data from AD to make custom signatures for everyone which has worked great for years. However a random group of users got the update to roaming signatures and the old "on device" signatures can no longer be used automatically for new messages or replies. You can create a new email and do a Insert -> Signature and they are all there but it won't let it be applied automatically. We have blocked the feature from being implemented on more machines using a registry tweak pushed through GPO ( https://support.portal.exclaimer.com/hc/en-gb/articles/5300182785053 ) but the damage is already done. So the only thing we can do now is to go into Options -> Mail -> Signatures, switch the drop down to "On this device", select all & copy, then create a new "cloud" one and paste it in. Again it was a random group of users but I do not want to do this for 300+ users in the future. So far haven;t been able to revert any of those new "migrated" users back.

There has to be a better way.

I have the same issue.
We don't want the signature default placed under every email (Via Exchange) because of shared mailboxes etc.
People have multiple signatures generated with AD info and info of the shared mailbox

I disabled DisableRoamingSignaturesTemporaryToggle.
Changed New and Reply registry location to
$OutlookProfilePath = "HKCU:\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles\Outlook\9375CFF0413111d3B88A00104B2A6676\00000002"
Get-Item -Path $OutlookProfilePath | New-Itemproperty -Name "New Signature" -value $SignatureName -Propertytype string -Force | out-null
Get-Item -Path $OutlookProfilePath | New-Itemproperty -Name "Reply-Forward Signature" -value $SignatureName -Propertytype string -Force | out-null

If there is a way to have something like this to online?

Thanks

I am also the same, The bit I can not figure out is the removal of existing signatures from OWA. They are not stored locally(that I can find) like the desktop app and I guess as part of this roaming profile half baked plan there are elements stored cloud site somewhere.

Any thoughts welcome

Thanks
