You send emails from a shared mailbox and would like for your own personal signature to be applied to the message.
There are two different methods for applying personal signatures to emails sent from shared mailboxes:
The easiest way to apply your personal signature would be to apply a client-side signature to the message in Outlook.
How to apply a client-side signature
When a signature is applied using a server-side signature rule, the signature that is applied to the message will depend on the permissions that have been configured for the mailbox in Exchange Online:
- If the delegate has send-as permission, the shared mailbox's signature will be applied.
- If the delegate has send-on-behalf permission, the delegate's signature will be applied.
Caution: Applying both send-as and send-on-behalf permissions will result in send-as permissions being used when sending an email.
