Description  

Send on Behalf is a setting in Exclaimer for Server-Side deployment only that allows to you send an email from a different From address, such as other users, groups, or shared mailboxes. In Exclaimer, this is evaluated in Server-Side deployment in conjunction with Microsoft/Google's Send on Behalf functionality. When the Exclaimer Send on Behalf setting is enabled, the recipient sees an email that states it has been sent by you on behalf of the other user or group.

This setting is only applicable when mailbox sending permissions in Microsoft/Google are configured as Send on Behalf. This setting does not apply when mailbox sending permissions in Microsoft/Google are configured as Send As.

For more information, see the 'What is the difference between Send As and Send On Behalf?' query in our Configuration FAQ.
 
As a further example, in the following scenario: 
Mailbox A sends on behalf of Mailbox B
 
Use 'Send on Behalf' sender is Enabled in Exclaimer
Details for Mailbox B are added to the signature.
 
Use 'Send on Behalf' sender is Disabled in Exclaimer
Details for Mailbox A are added to the signature.
 

Pre-requisites: To use Send on Behalf for Exclaimer emails, you must use both the Exclaimer setting and the Microsft 365/Google setting. 
For  instructions on setting up Send on Behalf in Microsoft/Google, see:
Microsoft 365: Send email from or on behalf of an Office 365 group and Give mailbox permissions to another Microsoft 365 user - Admin help.
Google Workspace: Send emails from a different address or alias.
