---Original Title: E Mail accounts---

I have 3 accounts.  Can access them all on web sites, but not on Windows Live Mail. They were OK, but not sure why this has happened. 

GMail account not working,others OK. Changed password several times, always changed it on accounts and settings, but to no avail. Took account off and tried to then add again, Ok until folders are downloading then they stop after few seconds,

The message I get......

Your IMAP command could not be sent to the server, due to non-network errors. This could, for example, indicate a lack of memory on your system.   

Configuration:
   Account: Gmail xxxxxxxxxxx
   Server: google.com
   User name: xxxxxxxxxxxxx
   Protocol: IMAP
   Port: 993
   Secure(SSL): 1
   Code: 800ccc0e

Not a memory issue.

Some while ago I had a problem and still have with 1 persons mail, but checked his address and other people have no issues with it.

Every time I try to access all accounts the message appears, and I cannot get rid of it. As follows...I have no need to send it now but would like to get the error message off.

The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for xxxxxxxxxxxx  (this gives my e mail address)  please contact your email service provider.

This was a group message bu then took the one off and tried to send on its own....still no luck.
