One of the things we get asked from time to time is how to set up automated signatures in Exchange Online.
While with an on-premise Exchange solution you can utilise 3rd party solutions such as Exclaimer – this isn’t possible in Exchange Online due to the shared environment.
However – you can still utilise the Forefront Online Protection for Exchange (FOPE) to automatically append either a text or HTML footer to the bottom of each message.
If you don’t already have access FOPE – put a service request to be granted access.
Once in, head to your domain service settings and add what you like – as shown below.
Bear in mind that embedded images aren’t possible as you would normally have with Outlook – however you can link to the image.
