Email Signature in Out of Office Reply
The email signature attached to out-of-office or vacation auto-responder messages, often a variant of the standard signature noting the absence and providing alternative contacts.
What is Email Signature in Out of Office Reply?
An email signature in an out-of-office (OOO) auto-reply is the signature attached to automated absence responses. Best practice OOO messages include: the dates of absence, the reason if appropriate ('on parental leave,' 'at the AWS re:Invent conference,' 'on annual leave'), an alternative contact for urgent matters, and the signature itself. The signature on an OOO message is typically the standard signature; occasional variations include adding a temporary banner highlighting the reason for absence (a conference attendance banner during the absence, a 'congratulations to me' parental leave note for those whose culture supports it). For organizations with centralized signature management, the OOO message can be sent through the same stamping mechanism (Exchange transport rule, Outlook add-in) so the signature is consistent. Microsoft 365 has native OOO functionality under Automatic Replies; Google Workspace has Vacation Responder. Both apply the user's outbound signature to the auto-reply.
