Do the Client-Side agents (Exclaimer Outlook Add-in and the Exclaimer Signature Update Agent) support MFA?

Yes, the Exclaimer Outlook Add-in and the Exclaimer Signature Update Agent utilize Microsoft authentication mechanisms that fully support MFA.
 

IMPORTANT! Exclaimer Signature Update Agent – Deprecated 

Exclaimer has deprecated the Signature Update Agent desktop application and no longer provides updates or support. 

Existing users: If you experience issues with the application, visit the Knowledge Base for troubleshooting guidance. If you need further assistance, raise a support ticket.

New users: Install and use the Exclaimer Outlook Add-in instead of the deprecated desktop application.
 
Will enabling MFA on the Global Admin account with which Exclaimer was configured cause any problems?

No, enabling MFA on the Global Admin account with which Exclaimer was configured will not cause any problems. The Global Admin account is only necessary to grant permissions for the Microsoft apps that Exclaimer uses. The account is not retained as a service account.

Is it possible to enforce MFA on all sign-ins to Exclaimer?

Exclaimer uses MFA to authenticate sign-ins on a per-browser basis. The initial login will require MFA, but subsequent logins from the same browser will not require MFA authentication unless the browser data is cleared.

Exclaimer Portal users can choose to configure Microsoft or Google SSO for their account; however, it is not currently possible to enforce that these SSO options are used.

Can MFA be used for portal sign in with username and password?
No, you must use either MFA (Google and Microsoft) or username and password sign in, not both.
