I am searching for an IMAP mail server for a very special setup.

UW-IMAP runs under Windows, there are both native compiled versions
and a Cygwin distributed package (the current version builds out of
the box).

* collect mails from several pop accounts

You use something else for that, like fetchmail (also available as
Cygwin package).

* all those mails should be collected to 1 local account

No problem for fetchmail.

* which should be accessible by IMAP
* simultaneously(!) by up to 5 users

No problem for UW-IMAP. By the way, IMAP works from inetd, which
Cygwin also provides, the other option with the native build does use
something else.

I think the last request needs to be managed by the mail client, which I
am free to change as long as it runs on win2k.

What do you mean by manage?

In a broad sense, manage as in create/delete users is not related to
the IMAP server, you do that at the OS level (i.e. create Windows'
users).

Currently I stick with mercury/32 and Thunderbird 1.5 & 2.0 and
encounter a lot of problems.

Thunderbird keeps IMAP connections open all the time and keeps a local
cache of the mail headers. When 1 user deletes a mail, all other
thunderbirds will see a corrupted mail folder where headers will no
longer match to their message bodies.

That's a server bug, UW-IMAP doesn't have that problem. Perhaps the
only issue with UW-IMAP is that under Windows you have to use unix
mailboxes which are not the best choice when it comes to performance
for large mailboxes. Dovecot is said to be better on this respect,
but I have no first hand experience.

So messages are only marked for deletion. As mail traffic is quite huge
(for what I am used to) thunderbird obviously is not able to purge
messages later on (inbox has 5000+ messages). Additionally thunderbird
gets confused with folder subscriptions, which will be discarded on
every client restart.

Not a problem for UW-IMAP, flagging, purging, folders, subfolders,
subscribing, all the usual with TB works fine. TB does have a
notation problem when creating subfolders for instance, but that is a
TB bug and it can be circumvented easily.

Currently this is a big mess and I am trying to find a nicer solution to
all this. I have to fulfill the requirements mentioned above, the
software is up to me to choose.

Has anybody a suggestion what to use?

One thing left out, in case you also need a mail server, I use Exim
(all under Cygwin) and the combination Exim+tmail doesn't quite work,
messages with attached images get truncated... I don't know where the
problem is since Exim by itself (actually Exim+imapd) works fine, and
tmail by itself also works fine.
