Outlook 2003 keep asking for password

I just added a workstation to a 2003 domain with Exchange 2003, and upgraded Outlook 2002 to 2003, now Outlook 2003 keep asking for a password for outlook.pst, I searched the users local folder, deleted all files in the Outlook folder, yet when I start up Outlok, it still prompts for a pw for outlook.pst, I deleted all the newly created files again and still the same happens.
Where else do i need to look or delete setting so when I start up Outlook it wont ask for this password again ?
I see the Exchange link is working as I can see the emails flowing in, but when the password box appears, I cant do anything, even cancel the box doesnt do much, the box just reappears and no access to Outlook while the box is active, only way to close it is CTRL-ALT-DEL but this also closes Outlook.

Greetings, DuffyS40 !

Do a search for .PST file, even in hidden folders, and with Outlook close, delete or rename them.

PST file default folder is located in C:\Documents and Settings\<user>\Local Settings\Application Data\Microsoft\Outlook folder. It is a hidden file. Open Windows Explorer folder and select Tools > Folders Options > View. Check "Show hidden files and folders". Click OK.

Best wishes!


Hi War1
I have located the folder and deleted all inside it, I checked the time stamps and they all timed around the last use so I know I am in the correct folder. Strange as teh station is part of an exchange 2003 domain so should be no more pst.

It seems that the new PC is not a domain member, just in a workgroup. Recheck the settings?

Hi Chris, checked, the station is a domain member, this is not the same password box you get when you are not a domain member, where you get 3 fields like username/password/domain.
In this case, its just a single box asking for the password for the file outlook.pst.

Do you have a PST that someone has set a password?  If so, use PST19UPG


Hi war1
Problem is..I cant even find the PST this error is referring to, I already deleted all PST/OST files thats outlook creates as soon as it starts (the date/time stamps confirms I am in the correct folder), and its a domain user logged in, just cant think where else to look..
Top Expert 2008
In Outlook, go to File > Data File Management. Check if there is a PST file there. See if you can delete it.

DuffyS40, any update?


Never found the answer, reinstalled XP and OL2003 instead..  :)
