ProblemWhen sending an attachment from the context menu in Microsoft Windows Explorer using "Send To, Mail Recipient", the e-mail will be generated without a signature. This behavior will occur even when a mandatory signature is configured through RES Workspace Manager.
CauseWhen files are attached to an e-mail by using the "Send To, Mail Recipient" in the context menu of Microsoft Windows Explorer, a subset of Microsoft Office Outlook is invoked called SimpleMAPI. This subset does not support e-mail signatures.
SolutionThis issue is not related to RES Workspace Manager and will also occur in an unmanaged session.

Select the appropriate signature when Microsoft Office Outlook has generated the email message.
