Our Microsoft Outlook 2002 users are encountering the situation described in the UW-IMAP FAQ:
7.19 Why did my POP or IMAP session suddenly disconnect? The syslog has the message: Killed (lost mailbox lock) user=... host=...
We do see these entries in our syslog. The FAQ gives two possible explanations:
1. Certain poorly-designed clients routinely open multiple sessions to the same mailbox;
2. Another cause is a background "check for new mail" task which does its work by opening a POP session to server every few seconds.
Anybody know which of these is the culprit with Outlook? Is there a work- around that will spare these users the annoyance of the "Your IMAP server has closed the connection" boxes? (Like a feature they can turn off to stop Outlook from opening multiple sessions, maybe?)
Hello Kai,
We have found that with Outlook, any other process opening a read-write connection to the same email folder will produce this error. [I.e., it is problem #2.]
If you are just running a single Outlook process and nothing else [except your MTA] is accessing your email folders, then you will have no issue. We have not found any feature in Outlook that will make it handle these disconnects more easily.
However, we have found that Mozilla Messenger DOES handle this situation very well and will automatically, and without warning dialogs, re-establish your IMAP connections after being broken by other processes.
