Error when running OcsUmUtil.exe on Lync server

Question

We have a very simple system, consisting of one Lync server, one exchange server.
I have followed all steps to integrate Exhange 2010 UM with Lync 2010.

All goes well until I try to run the OcsUmUtil tool on the Lync server. When I try to add a contact, I get the following error:
"There was an error while trying to create the new contact object in Active Directory. Make shure that the account you are using has persmission to write to active directory, and that the name you have shosen for this contact is unique. Object reference
not set to an instance of an object."
The account I use certainly has all the required permissions, and the name is unique.
So, how do I continue????

Answer 1

Yes, if no luck, would you please run the New-CsExUmContact cmdlet to create any contact objects required for your deployment. For example, run the following to create an AA and an SA contact object:
New-CsExUmContact -SipAddress "sip:[email protected]" -RegistrarPool "lspool2.lcscorp.lcesa.pri.local" -OU "HostedExUM Integration" -DisplayNumber "[phone]" -AutoAttendant $True
New-CsExUmContact -SipAddress "sip:[email protected]" -RegistrarPool "lspool2.lcscorp.lcesa.pri.local" -OU "HostedExUM Integration" -DisplayNumber "[phone]"
