I want to modify the details (like subject, description, st. date, end date
etc.) of a particular appointment from SQL Server 2005 on the basis of ID. As
now I am writing this code but this would update first appointment in Outlook
2007.

Code:

Dim sQuery As String

oXMLHttp.open("PROPPATCH", stURI, False, Me.UserNameAlias,
Me.Password)

sQuery = "?xml version='1.0'?" & _
"aropertyupdate xmlns:a='DAV:'
xmlns:m='urn:schemas:mailheader:' xmlns:cal=""urn:schemas:calendar:"" " & _

"xmlns:dt='urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/' " & _
"xmlns:mail='urn:schemas:httpmail:' " & _
"a:set" & _
"arop" & _
"mail:subjectAppointment with PM regarding
dismissal of Atul /mail:subject" & _
"/arop" & _
"/a:set" & _
"/aropertyupdate"

oXMLHttp.setRequestHeader("Content-Type", "text/xml")
oXMLHttp.setRequestHeader("Brief", "t")
' Send the query.
oXMLHttp.send(sQuery)

thanks in advance.
