It really looks like a server problem to me. From: [email protected] [mailto:[email protected]] On Behalf Of Dave Vantine Sent: Saturday, January 24, 2015 10:28 AM To: [email protected] Subject: [Exchange] Outlook IMAP problem I have a customer that is using Network Solutions email. One of the users is using Outlook 2010 and connects to the mail server with IMAP. Most of mail is being stored into a local PST file. They suddenly started having an issue get the following message multiple times during the day "Your IMAP server wants to alert you to the following: Fatal Error: Cannot allocate memory" I called Network solutions and they said the users mailbox was full however when I check their mail from the Web interface it indicates that 458MB of 6 GB is used. (as I indicated most of the mail is local in a PST file) My Google Foo has come up with nothing and am hoping someone may have experienced this. I am not sure it is really the server that is causing the error to get thrown but am not sure where to diagnose it further. Network solutions is useless on their end. Thanks Dave Vantine
