When a sender from outside the domain tries to send an email to one
our exchange clients, they will get this error:
The user(s) account is temporarily over quota.
The email address that is having the problems isn't the default SMTP
email address for the domain. We haven't used any quotas on our email
boxes because we are small, and there is no reason to. So, the quota
isn't even a factor. People that try to send to this other SMTP
email address from outside the domain receive the error above. All in
house mail to that non-default SMTP address arrives without any error.
There is only one person's account that this is happening to.
Everyone else can receive their mail from outside the domain to the
non-default SMTP email address. We looked at how the individuals
account was set up on the server and it's no different than the other
employees. The only thing different about this individual is that
he's running Windows XP, and I don't think it's a workstation issue.
We've tried removing and adding his account again as well.
Any thoughts would be much appreciated.
