Hi,

I recently upgraded a laptop from Outlook 2000 to Outlook 2003 and moved
from pop to exchange at the same time. Now I can't open the users PST file.
It asks for a password that it didn't need before (in Outlook 2000 using pop
on laptop). I took the pst file to another machine with Outlook2000 on, but
the same thing happened. It asked for a password. I tried it on Outlook2007.
Same again. I tried running pst19upg. This exports fine but then can't create
the pst file from the psx file, it errors (this strips the password
apparently). I ran the inbox repair wizard. It found corruptions that I asked
it to fix. Tried to open pst - same prob, it wants the password.

I am very confident there was no known password on the pst file before. I
opened outlook on the laptop several times without having to enter a
password.

I copied the pst file before starting any work. same prob on copies, it
wants password.

One thing, it was on a pop account before. I am now using it on a exchange
server account. Could it be seeking the pop password? Is the pst file tied in
to this password in some way? There was very little opportunity for the pst
file to corrupt, as it worked, then I copied it, then I installed Outlook2003
and set it to use Exchange Server instead of pop, then it didn't work anymore.

I am getting desperate here. Last resort will be to get laptop, re-install
Outlook2000 and set up pop again in the hope that works. I am reluctant to
get a password cracker prog as it seems it may be more corrupt than password
protected.

Any advice?
