|Jennifer - read the original post. His problem is that AFTER he does what you posted, there is no option to select 'pst', therefore you cannot add one.|
I have two systems side by side, and one of them will not allow me to add pst files, the other will. They have the exact same group policy, version of Outlook, etc. I am still investigating.
The common fixes for the OP's problem (which almost always resolve this) are:
1) rename ‘mapisvc.inf’ file to 'mapisvcOLD.inf' - this file is found in two places: C:\Windows\System32, and C:\Program Files\Common Files\System\MSMAPI\1033
If that doesn't do it, try this:
2) in REGEDIT, change the registry key. Usually (DisablePST = 1) was added and set to prevent the creation of PST files and hence no data types appeared in the list. When you modify the value of the registry key back to 0, you can add PST files again. You need to make the change to all versions of the key.
