I am having trouble with outlook 2003 mail. I have been using outlook for awhile to check my mail and everything was working fine until yesterday. Now I cannot check my verizon mail. My msn is working fine though. When I click the send/reciev button verizon's recieving thing always has an error. I ahev no clue what is wrong becuase I never changed anything. If anyone can help I'll be etirnally grateful! Thanks in advance! ~Danielle~
