Having the same problems as others when trying to access emails, getting the Mailbox Unavailable error page, not affecting all email accounts though
I'm having the same problem, reported it on this forum a couple of days ago but still waiting for a PM to sort the problem out.
My account was hacked some time last year, but had seemed to of got past that problem until this issue 3 days ago
Sorry to hear you have been unable to access your mailbox.
I'm going to send you over a PM so I can look into this with you from there.
