Cannot open outlook 2003 after migration from outlook 2000

[Guest]

Hi,
I have a problem with a couple of my user.
first we are using exchange 2003.
I migrate outlook 2000 to outlook 2003 everything went fine but a couple of
my user cannont open outlook, the error message is saying that it cannot
contact exchange, maybe there is a network problem, contact your admin...
and outlook is closing.

I create a pst with the user email, I have deleted their ad account and
exchange mail box.
I create a new account.
I lauch outlook 2003 it works fine.
I put everything that was in the pst file into is outlook folder on
exchange, same thing with is calendar.
everything is fine, I restart the computer 2-3 time, still working fine.
after maybe an hour, I re-lauch outlook and I have the same error message,
and I cannot open outlook anymore.
the solution: downgrade to outlook 2000.

One thing that all those user have in common, they have a calendar with a
lot of stuff in it.

Anyone have an idea to fix that problem, I don't know what to do.

thanks for your help.

Have you tried opening Outlook with /cleanfreebusy or /cleanreminders switches?

 

[Guest]

is it gonna delete anything?

Have you tried opening Outlook with /cleanfreebusy or /cleanreminders switches?

 

[Guest]

and do I need to lauch outlook with that switch everytime or only once?

thanks

You shouldn't lose anything and you should hopefully only have to use the
switch once. Let me know what happens.

 

[Guest]

unfortunaly, it's not working, I tried all the switch with no luck...
It is a real pain!

 

[Guest]

Out of curiosity, how did you bring the user's PST back? What method did you
use?

 

[Guest]

I open the pst, and use drag from the pst and drop into his mailbox.

this morning I create a new user with a copy of a user that have that
problem and I can't even open outllook.

I think I will place a call at Microsoft next week if I cannot figure out
what is the problem.

Ok here is the solution that I found:

start > run > REGEDIT

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
Lsa\[Kerberos]

create new folder called Parameters
create new dword called MaxTokenSize
value 35535 decimal (should appear as 0000ffff)

Reboot the pc try opening outlook.
