Hi,

According to Article 813349, "If the .NET application assemblies do not
reside directly on the Exchange Server, Microsoft recommends using WebDAV."

But WebDAV can't access Recipient table. So WebDAV can't retrieve
Undeliverable email contents (Non Delivery Report). For technical details,
please go to Enterprise --> Exchange Server --> Exchange2000.development.
Search "WebDAV" for "Re: Detect Undeliverable Email using WebDAV".

I was told MAPI is the only way to access Recipient table. But MAPI is NOT
supported by .NET Framework per 813349. That's why we implemented WebDAV.

My question is if there is a way to at least workaround the problem to
retrieve Recipient table to get fields like Undeliverable email addresses,
reason codes, diagnose codes, etc.

I don't intend to discuss the technical details here. I just like to know
what support .NET Framework provides to access Undeliverable emails (Non
Delivery Report).

Thanks.

Hello,

There is a limitaiton of WebDav here. I have to say there is no good answer
for this question. The only work around is to get back with MAPI. As I
know, there is some third party .NET wrapper for Extended Mapi which can
work in .NET application. You may find them with a internet search.
