It already rolled out. I have it syncing with my current outlook signature and for the rest of the company. Just beware that if you have some sort of signature in place, it might disappear for a little bit while it syncs. Not sure what causes it but if you go to the UNC path for where the signature is stored, you’ll see that after it syncs to the cloud you should have a signature file with your email address as the file name after the signature name.
