Server responds System I/O Error when trying to Purge Deleted Messages
I am trying to resolve why one of my end users is unable to purge his deleted messages on our IMAP server. He receives a System I/O Error when he either tries to use the Purge Deleted Messages command in Outlook, or if he tries the Expunge command off of our server through webmail (we are using SquirrelMail). I've searched for information on the error on SquirrelMail's site - but cannot find anything. Please help! I am new to working with IMAP servers.
