Have been having problems with some email addresses on a 1and1 domain.
There are 11 addresses and all work using webmail however when using Outlook four of the addresses have suddenly started to fail because the server does not recognise the password. The passwords being used have been checked and are correct. (The other addresses still work perfectly)
Having checked with 1and1, the only solution they can come up with is to change the password, however that hasn’t worked, and doesn’t explain why the password works when using webmail I do know from their helpline that they have had problems recently with the particular server that is being used.
I believe that this is a server problem at 1and1’s end but wonder if others have had this problem and if there is any other solution
I run three websites on 1and1 mshosting servers and one on a linux server, and only have intermittent problems with different email addresses. Sympathies, but cannot help, and have no idea what might be wrong.
