Hi, thanks for your awesome tool!
Signatures + OOF are working excellent for my local Outlook client.

Sadly it does not create the signatures in OWA.
OOF works fine in OWA.

It also does not delete the user created signatures in OWA.

powershell.exe -file .\Set-OutlookSignatures.ps1 -DeleteUserCreatedSignatures $true -GraphOnly $true -Verbose

Hi @swissbuechi,

this is not an error in Set-OutlookSignatures, but a Microsoft problem that is unaddressed for nearly two years now.

Please have a look at the README file, chapter "16.25. What about the roaming signatures feature in Exchange Online?" (https://github.com/GruberMarkus/Set-OutlookSignatures#1625-what-about-the-roaming-signatures-feature-in-exchange-online). It will explain the root cause and possible workarounds.

Kind regards

Markus
