OnConnection

[Guest]

Hello,
I have a problem with my add-in, that some simple OOM or MAPI functions fail
in the context of the OnConnection event - my add-in inherited from the
_IDTExtensibility2.
As an example, the GetFolderFromID() function throws a_com_error exception
with unknown error( 0x96a40107 ). This occur with some folders in a PST.
Other folders and other PSTs don't have this problem.
The same function succeeded when I call it with the same EntryID & StoreID
but after leaving the context of the OnConnection event.
Now, simply, the question is, does all the PSTs loaded completely before
linking (calling OnConnection)with the add-ins?!!!

Use OnStartupComplete callback instead - by the time it is executed, Outlook
already has a valid MAPI session.

Hello Dmitry,
I tried it and unfortunately it didn't work!!!
I think that my MAPI session already valid... The problem doesn't exist with
the two default PSTs (Personal&Archive).. but it is valid with another PST
that I added to the outlook... when I call the GetFolderFromID for any folder
it it within the OnConnection or OnStartupComplete; the exception triggered.
But when I call the GetFolderFromID of the same parameters within a call to a
button I added to the Outlook toolbar, the function succeedeed.
I think that this is one of many of the strange behaviors of the Outlook.

Thanks.

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

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?

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.

 

[Dmitry Streblechenko]

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

Yes, one PST, and not always
There is nothing different in this PST, unless it was empty, but I put some
mails in it and the same problem still. On another testing machine, the same
problem found with an OST file.

Is it password protected?

No at all.
I left this issue now, and when I find anything new, I'll inform you.
Now, I have new questions and I'll put every question in a separated thread.
Thanks Dmitry.
