Once again Outlook for Mac 2011 won't connect to my Exchange server.

Won't accept user passwords or user name according to the popup window.

Have also tried connecting to server when directly connected to the same network via ethernet as the server with same results.

All my other Exchange enabled devices work fine- Ipod, Ipad, Droid phone and Windows Outlook 2007 with same user and passwords.

Have also tried dumping the accounts, folders, etc per previous directions, it worked once but not now.

Psw

Just changed my password because someone had tried to 'hack' me.

With the change, I lost my signature showing name, ph. #, etc.

Can't find theplace to re-add signature.

I am not interested in adding a picture.

Invalid phone number
Downloaded Microsoft + seven to my Android phone but the whole program did not install. Missing the menu bar. Cannot get into the folders section. Cannot brouse any folders or sub folders All the rest works well. Who has a fix?
Thank You
