The best way I know of is to use GetLastError.

Certainly when iterating 14000 items you could run into the 256 RPC channel
limit. After how many items does your code fail?

Dear Ken,

I'm running the code on the same machine as where Exchange is running. One
of the mailbox items (being 'Sent Items) on which this call fails contains
14.000 messages.

Still, if there is a limit considering this RPC interface surely there
must
be a way by code to find out the exact cause of the PartialComplete?

How can I drill down in the MAPI interface after I get this
PartialComplete
to find more details on why this result was returned?

Thanks ahead
