In Sept. I lost my main mail account due to error 3204 & so I then created a new mail account & tried to contact all my addresses to inform them of new address.  ( I lost all contact information because of error 3204)

My new mail account has worked for 2 months & yesterday I again had an error 3204.  I contacted Microsoft chat & tech worked with me for 30- 40 minutes trying to solve problem & then hung up without solving problem.  I have tried everything recommended & no solution. 

I haven't deleted the account & then tried to recover it yet hoping to find a different solution because that didn't work before. 

Does anyone have a solution to this problem? I Sure need help.
