If you haven't tried already, try deleting the profile and recreating
the profile in Outlook.

Subject: [exchangelist] E2K / Mixed Mode / Clients hang
http://www.MSExchange.org/
Dear list,
After migrating some test users to the exchange 2000 server, we are
discovering some issues.
Config as followed:
- Mixed mode site (one 5.5 server / one exchange 2000 server)
- Site integrated in organization with several different sites
(some also in mixed mode, some plain 5.5)
- Between some the sites are packet filters / firewalls which
don`t let unknown traffic pass through
The issues we discovered are:
- Outlook clients with E2K-mailboxes often hang on startup or
while trying to delete an unread read-notification (?)
- While hanging we are discovering the clients want to contact
several exchange 5.5 servers in different sites --> running against
firewall --> timeout --> outlook freezes
- The target ports are 135, 139 (netbios) and 445
(Microsoft-ds)
- Clients with mailboxes on the old 5.5 server do not have
these kind of problems
So my question is, why do the exchange 2000 clients want to talk to so
many 5.5 servers? Is it possible to turn this communication off? Since
this behaviour is restricting the usability of the new clients and we
don't want to open these "unsecure" ports on the firewall for all
clients, I need a solution soon.
Any comments and hints are welcome.
Thank you in advance.
Christian
