[Evolution] Evolution - Account is over quota

[Evan <evangerard gmail com>]

Greetings.

I'm using Evolution 2.8.1-0Ubuntu4 on Ubuntu 6.10.  I've set up an
account to my Exchange server and I've been able to get mail
successfully for months.

Currently I cannot send e-mails.  The error message is as follows:

Error while performing operation.
Could not send your message.
This might mean that your account is over quota.

I can access my Exchange account from another work computer (XP)
without any over quota error messages.  I've tried to search online
for the answer to no avail.

Has anyone else experienced this problem and have a solution?  Thanks.

Evan
