Re: ¿Is it possible to create a contact in Exchange 2007 with webdav operations?

Thanks by your help Glen.

After I pasted your code some bugs appeared which I could correct except the
one I mention in the following lines:

List<DLEntry> DLEntries = new List<DLEntry>();

Error 1. The type or namespace name 'DLEntry' could not be found (are you
missing a using directive or an assembly reference?)

I understood that the bug appeared because C# wasn't able to recognize
DLEntry as a valid data type. Do you know how I could overcome the problem?


Cheers, Memo.

p.d. thanks in advance ..

The code to delete entries is the same as to add or update a Distirubution
list your just adding or removing elements in the value array you do need to
write some code that will decode the property to identitfy the value you
