WrappedPST - ReadOnly Message Store Provider

Category: MAPI

We are creating a readonly wrapped PST provider (very similar to how Wrapped PST). The reason is
that we have some users that deleted their profiles or accounts and they still want to load the PST
file to get some stuff off of it. So, I made a read-only message store provider only (no transport
provider) so that the user can go into the "Data Files" section, click on "Add" and select

our
product which then we popup a "Open PST file" dialog box for the use to select the PST. That work
just fine. It's only when the user want to access it via Outlook that Outlook display this error:

This error usually appears if the OST or PST file you are using is:
Unavailable
Protected with file permissions
On a share on a server and the network is down
Corrupt

To correct this problem, store the OST or PST file on the local computer.

You may also want to run the scanost.exe and scanpst.exe tools to verify file integrity.

More information about this error message online.

The call that is failing that cause that error is in our CMSProvider::Logon when we call
PST_MSProvider::Logon which returns 0x08004011c (MAPI_E_UNCONFIGURED).

How can we get PST_MSProvider::Logon to accept the PST/OST file?!

Regards,
Shawn
