When I add a cell phone number in active directory for an Outlook signature, it comes through fine. Replies, forwards, new mail..it all looks the same...unless you are replying to an email sent from a phone. I have tested this on several different users and get the same result, it always puts the cell number except when replying to an email sent from a phone. Any ideas? I'm a low level IT guy just starting out, so I hope this isn't a stupid question. If so, I apologize. Thanks in advance.
