Custom User Attributes
Even if you do add some custom attributes in AD, you will not be able to leverage those for email signatures, as only some predefined attributes can be used for that. Just in case, here's how to add attributes to Azure AD: https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-sync-feature-directory-extensions
VasilMichev thank you for your reply! Even not with third party tools like the CodeTwo Connector? We understand that mail flow rules are quite limited in Exchange and tend to use a third party solution for it.
As per https://www.codetwo.com/userguide/exchange-rules-pro/custom-placeholders.htm#custom-attributes-section the program would allow to add AD attributes. But as we are using the O365 subscription only, I'm not quite sure if and how this would allow me to edit the User attributes.
That's a question you should be asking them, we dont discuss third-party products here.
