I am using Outlook for Mac and I have a problem with signatures.  Sometimes when I am replying to, or forwarding an email, my signature will change font size and font type.  Any ideas?
I sent a request to add someone to messenger.How will I know if they accepted? The email address was showing the minute I sent the request.
 I updated my contact list.  I deleted some names and I added new information to some contacts.  I can not find a place to save the newly updated contact list.  When I go back to my home page to send an email I still get the old contact list. 
I went into manage groups and added a new group with contacts and deleted some unused groups. When I try to compose a new email, the change doesn't show up in the categories area when you click "To". Only the groups that existed before I added/deleted are showing up. How to fix?

I'm also haviing problems getting into my contacts, this has been going on for weeks.  What's going on???

I can't see any of my contacts they don't even come up anymore. When I go to the page that you now call people it is blank and says a problem occured. Even when I try responding to an email that persons address has to be typed in what is going on?
