Did you compile neon against openssl or the default internal ssl? I
used against openssl.<br>
Make sure you have the rootca from the exchange server in
/etc/ssl/certs<br>
<br>
The message/warning looks like the Exchange server expects a
kerberos authentication. I have no experience with the EWS calendar
module and using kerberos to authenticate.<br>
<br>
Hope this info helps.<br>
