Comment 6 for bug 150571

Mine is not locking up, but is indefinitely popping up error messages saying that the IMAP server is not available (attached screenshot). On a small number of cases it actually fetches mail from this account, and works for the other accounts, but is consistently failing to find any messages from this one. The settings for their server, and instructions for Thunderbird, are at http://8help.osu.edu/2148.html and the IT staff suggested that I set the cached connections to zero, but every time I open Thunderbird, it defaults the cached connections to 5.
