Limitations of organization wide signatures

You can't do the following when managing email signatures in Microsoft 365:

• Insert the signature directly under the latest email reply or forward
• Display server-side email signatures in users' Sent Items folders
• Embed images in email signatures
• Skip lines which contain variables that couldn't be updated (e.g. because the value wasn't provided for a user)

Hi @IniobongNkanga-8038，

Thanks for posting your question in the Microsoft Q&A forum.

According to your description, when you try to set a global email signature from an Exchange rule, it doesn't work. To find the cause more accurately, you can try to provide the following information:

1. Do you have any error messages?
2. Are you creating the signature in the Microsoft 365 admin center or through the EAC?
3. You can use the command Get-TransportRule | where {$_.ApplyHTMLDisclaimerFallbackAction -eq 'Wrap' -and $_.FromScope -eq 'NotInOrganization'} to see if the value Wrap is used, which may affect incoming mail from external senders.

Refer to: Organization-wide message disclaimers, signatures, footers, or headers in Exchange Online | Microsoft Learn
