We've been plagued with intermittent, bizarre IMAP email behaviors over the past few months. The provider is GoDaddy. The problems seem to be most prevalent on our most active email address account, and shows up most frequently on a machine running Outlook 2010.
We've had emails reappear in the inbox that we deleted, causing multiple attempts at deletion, and also emails come into the inbox then vanish. Sometimes emails take up to an hour to arrive. Just recently, the Outlook 2010 client lost the password for the account plus one other.
Thinking that this account's pst file is corrupt, I deleted the account on this machine and recreated it last night which took hours - the account has 1.3 GB of email with multiple sub-folders (I have the accounts in Outlook set to download the full contents of each email instead of just the headers because we have an archiving program on the machine that requires it). So far this morning, things are stable.
However, I'm thinking that this is just a band-aid and there is something else going on. GoDaddy's tech support is useless here. Their position is that if they "check" the account and see no problems, if the webmail portal is working
ok, an email they send appears in the inbox in the webmail portal, and if the Outlook settings are ok, then it is not their problem - it is a client issue. Perhaps, perhaps not, but it would make sense to be able to offer some additional support for
email clients when things like this start to happen. GoDaddy's only solution here is to "re-sync" the account(s).
Anyway, here is our configuration:
1) All communications on all machines/devices are SSL (ports 993/465)
2) Two Outlook 2007 clients - 8 IMAP accounts on one, 3 on another
3) One Outlook 2010 client - 5 IMAP accounts (this is the client/machine where most of the problems are occurring)
4) One Thunderbird client on a laptop - 8 IMAP accounts
5) Three K-9 clients on three Android smartphones - 6 IMAP accounts on one, 1 IMAP account on the other two
6) iPad using stock email client - 8 IMAP accounts
The devices/machines run a mix of anti-malware suites - F-Secure on the office machines, Norton on the laptop, and Lookout on the Android phones. F-Secure's email filtering is turned off since it was causing issues earlier.
So, I'm at a loss to pinpoint what is causing this behavior. Is it a bad IMAP client on one of the machines or devices not following the IMAP protocol? Is it purely pst file corruption? Too many devices?
If anyone has any ideas, they would be greatly appreciated. Thanks!
