Live 2012 mail always stops sending and receiving when emails are deleted.  Error message is bad user name or password?  There is nothing wrong with either.  I cleaned up my in box on one computer and it promptly stopped sending or receiving with one email, I use three emails and other two are working fine.

The second computer worked for 4 more days and then stopped sending or receiving from the one account.  This condition will clear itself after several weeks and download everything from the time it stopped?  I say always because this is the fifth time it as happened and it did this on win7, 8.1, and 10.
