Comment 7 for bug 361993

Same here (karmic) on Kubuntu.
openchangeclient from command line, same result. internal works external does not work.
I can provide some more details from the exchange server that I got by mail:

Maybe the problem is this long string:

To: Peter <email address hidden>

I think, the part "20ADMINISTRATIVE+20..." must look like:

<IMCEAEX-_O=NORTIW_OU=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=CLUSTER is at CURRENTCLUSTERHOSTNAME.nortiw.tooriw.local

Maybe that's the problem??

P.S.
I changed IPs and hostnames in the above output.
