WebDAV and Exchange Archiving

Hello,

I have a question regarding how webDAV accesses the Exchange store. Does it
go directly to the mailbox, or does it go through the Hub Transport?

We are doing an Exchange calendar integration for our application, and it is
important that our method of accessing Exchange does not bypass the
archiving functionality.

Additionally, we have chosen WebDAV as our method of integration because it
is backwards compatible with older versions of Exchange. What would be the
advantages of using the Web Services or .Net Extensions to synchronize with
exchange appointments?

Thanks for any help,

Glenn Thimmes

Hello Glen,

WebDAV uses MAPI internally. It won't go around your archiving solution.

But for Exchange 2007 I would probably go the WebServices road (Since WebDAV
is practially dead). It's a cleaner approach since you can access all the
Outlook fields directly and strongly-typed. Which is not the case with
WebDAV. It can be somewhat tricky because some outlook fields map to two or
more other fields.

Kind regards,
Henning Krause

Thanks for the response. This answers my question.

The reason why it is necessary for me to go down the WebDAV road is
backwards compatibility of this integration module. We have customers going
back as far as Exchange XP. We've got to give them a little longer before we
can say we only support 2007 for calendar synchronization.

Thanks,
