Re: Cannot create calendar appointment via webdav
How are you actually trying to use the code eg are you writing a console
application,ASP.NET or a web service (or are you trying to write something
in VB6). You will need to change the code from that KB to be able to
authenticate via FBA. There are samples for doing this in
http://support.microsoft.com/?kbid=891748 and
http://www.infinitec.de/exchange/howtos/webdavwithfba.aspx. Another quick
sample i use in VBS to handle FBA looks like
Set req = CreateObject("Microsoft.XMLhttp")
servername = "servername"
mailbox = "mailbox"
domain = "domain"
strpassword = "password"
strusername = domain & "\" & mailbox
szXml = "destination=https://" & servername & "/exchange&flags=0&username="
& strusername
szXml = szXml & "&password=" & strpassword & "&SubmitCreds=Log
On&forcedownlevel=0&trusted=0"
req.Open "post", "https://" & servername & "/exchweb/bin/auth/owaauth.dll",
False
req.send szXml
reqhedrarry = split(req.GetAllResponseHeaders(), vbCrLf,-1,1)
for i = lbound(reqhedrarry) to ubound(reqhedrarry)
if instr(lcase(reqhedrarry(i)),"set-cookie: sessionid=") then reqsessionID
= right(reqhedrarry(i),len(reqhedrarry(i))-12)
if instr(lcase(reqhedrarry(i)),"set-cookie: cadata=") then reqcadata=
right(reqhedrarry(i),len(reqhedrarry(i))-12)
next
stmsgbody ="Hello Fred <BR<BR>"
stmsgbody = stmsgbody & "What to get some coffee Mate, Meet me downstairs in
ten<BR><BR>"
stmsgbody = stmsgbody & "Cheers<BR>"
stmsgbody = stmsgbody & "Barney<BR>"
szXml = ""
szXml = szXml & "Cmd=send" & vbLf
szXml = szXml & "MsgTo=address@youdomain.com" & vbLf
szXml = szXml & "MsgCc=" & vbLf
szXml = szXml & "MsgBcc=" & vbLf

Re: Cannot create calendar appointment via webdav
I worked on the project in stages, first an unsecure non fba server then
modifying the code to work with the next level of security.
It turns out it's one of those scratch your head issues, the code was
rewritten, using all the same techniques in a new project and now it appears
to be working.
Thanks for the response Glen, if we can figure out what was actually causing
the problem I will post it here.
