The user is applying signatures to emails in Outlook and if the user selects multiple emails from Outlook and chooses to forward these, a new email is opened with the emails attached.
This new email does not contain a signature.
This is the expected behaviour of Outlook and cannot be changed by Exclaimer.
The user will have to manually add a signature from the drop down ribbon in Outlook.
