The following problem has been around for a very long time: users should use standardized signatures for emails, preferably across all devices and clients. Until now, this has required additional software to create and manage signatures.
Exchange Server itself currently only offers the option of centrally managing signatures for OWA. Additional software must then be used for Outlook and ActiveSync clients.
Jeff Guillet has made the suggestion to save e-mail signatures in the mailbox and thus synchronize them across all clients. The proposal has been heard by the Outlook and Exchange Product Group and it is now up to the users to decide whether it will be implemented.
I think it's a great idea and have already cast my vote. Anyone who would also like this option should also vote for its implementation.
You can cast your vote here:
Jeff's idea is already the number 1 most requested feature. So vote and keep your fingers crossed that it will be implemented.
Jeff's article can be found here:
Update 13.01.2019:
The article is a bit older now, but you can and should still vote for the signatures in the mailbox.
I hope that many more votes will be collected this year so that the desired feature can perhaps be used with a Cumulative Update for Exchange Server.
However, a few more votes are needed for this to happen. There are currently 6653 votes (as of 13.01.2019), putting the idea in first place among the most requested features.
Second place currently has 1969 votes. The more people vote, the more likely it is to be implemented! So go on, vote!
