So it only happens for one particular PST, not for any other PST or mailbox,
right?
Is there anything different about that PST?

I'm shocked just like you...
Yes 100%... I'm getting the StoreID and EntryID by looping for all PSTs
and
sub folders. And to be sure, I copied the StoreID and EntryID from the
Outlook Spy -GREAT PRODUCT- and used them as constants(GetFolderFromID(
"xxx", "xxxxxx"), and the same error exist with this strange PST when
calling
from OnConnection or OnStartupComp. And I used the same call to
GetFolderFromID in a handler for a button, and it succeeded.

The error looks like MAPI_E_INVALID_ENTRYID. Are you absolutely, 100%,
sure
that the entry ids belong to a store that exists in the current session?
Where do these values come from?

Do you specify *both* the folder and the store entry ids when calling
GetFolderFromID?
