The company I work for has had pst files on a network share for many
years now (on a win2k server and, since about 1 year, that is since I
came, on a gentoo/samba server). I still haven't seen any problems (a
part from the mentioned pc freezing issues), but our network and servers
have a very low load...

I've been thinking about implementing an imap server for some time
now... I hope I'll have time to get rid of "personal stored" e-mail as
soon as possibile...

We don't have neither of the two, so I guess I'll be safe :-)
