Dear Forum members

I would like to move a huge GW archive from UserA to UserB. UserA is leaving and UserB will take over her work and needs access to old emails. According to this TID : moving is possible. I have to set up a password for the archive then rename the directory to the represent the new users FID. Unfortunatly it wont work. All I get is a d019 error and a password box whicj wont accept any password.
My question is how can I set up a password for the archive? Or what password is needed? The online/LDAP/GW password?
