MS Exchange mailbox maintenance


  If an Outlook user downloads mail via pop3, and Outlook is not configured to keep a copy of the message on the server, how long does it take for Exchange 2003 to remove the mail from the user's  mailbox?

 I disabled Outlook keeping a copy of the message on the server today, but I noticed Exchange still shows the same amount of email in the user's mailbox through Exchange System Manager.

It depends on how long your mailstore retention is set for:

If you download emails through POP3, the messages are deleted from the e-mail server by default after they are downloaded.

look the configuration once again, and try downloading ensuring that the sync is complete and no errors.

Yes the sync is complete, and Outlook is configured not to keep a copy on the server. Yet the mailbox message count is not decreasing in Exchange System Manager. I believe alanhardisty is correct with the mailstore retention setting. My system is set for 30 days. I have Outlook set to clear messages now because Outlook was duplicating downloads, and would randomly download the entire message store, even though the messages were already downloaded previously. Searching around I found that Outlook has had quite a history with this problem, and it is linked to the "keep a message on server" option.

if the download fails from completing the download, the messages are not removed from the server.
