Using WebDav to delete mail from a MS exchange account

Question

Hello,

I'm trying to delete email from a MS exchange account using vb and webdav. So far I have managed to connect to the exchange server and retrieve emails but I am struggling to find any information to help with my problem. I obtained the emails using a SQL like select query but webdav does not support a similar SQL delete query and I'm totally stuck. Any help would be greatly appreciated.

Cheers in advance
