I'd like to start a thread on the whole issue of IMAP performance. Here are
the issues that I have encountered w/ a bit of background.
I'm a long time Outlook Express user. I have one pop account that I use,
and I attach to my office Exchange server via IMAP. This has been my
configuration for years, and it has worked flawlessly under Outlook Express
throughout. Other IMAP clients, such as Thunderbird, have not performed as
well as OE, so it was with some degree of trepidation that I took the plunge
into Vista and Windows Mail.
POP3 and SMTP work fine, I have no complaints. IMAP, however, is a complete
dog.
Header downloads work fine. But, clicking on a new message will often take
a full minute or more to display. More often than not, the download of the
message will never occur, or the progress bar will march part way and then
stop. The only way to get messages in those circumstances is to click
outside of the IMAP account folder tree, and then back in. Usually in the
second round, messages will download. I often get the remote server timeout
error while waiting. Even if I wait longer, nothing happens. The only
thing that works is click out and then back in to an IMAP folder.
Message deletion is doubly painful. Deleting single messages often works
fine. Deleting multiple messages displays a "modal dialog box" stating that
the messages are being deleted. Of course they don't delete, and I can't
close the dialog. The only way out is to kill Windows Mail in the task
manager.
Here are some of the things that helped improve matters:
1) from a command prompt, type:
tcp set global autotuninglevel=disabled
This disables some of the new TCP packet size features in vista that seem to
be incompatible with the rest of the universe. This helped considerably, by
the way.
2) Under Tools/Options/Send, turn off "Automatically Complete email
addresses when composing"
3) Under Tools/Options/Advanced, turn off "Use the deleted items folder with
IMAP accounts"
Although the above steps improved matters, the issues I mentioned still
remain. So far, Vista represents a major drop in productivity for me.
For seven years now, I've been a Microsoft Partner. Never have I
experienced such a dearth of information on such a highly critical topic.
