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.

http://blog.schertz.name/2010/11/lync-and-exchange-um-integration/

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????

 

Hi, would you try to run the following cmdlet in Lync Server Management Shell to grant the proper ACLs on the contact objects.

Grant-CsOUPermission –OU <OU or Users container DN>  -ObjectType contact

Hi!

 

I tried that, but I'm not shure what the input to the command should be... should the OU be the same as the one I'm pointing to when I'm adding a contact with the OcsUmUtil? (for example dc=acmo,dc=com)

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:HostedAA@lcscorp.lcesa.pri.local" -RegistrarPool "lspool2.lcscorp.lcesa.pri.local" -OU "HostedExUM Integration" -DisplayNumber "+14257273538" -AutoAttendant $True

New-CsExUmContact -SipAddress "sip:HostedSA@lcscorp.lcesa.pri.local" -RegistrarPool "lspool2.lcscorp.lcesa.pri.local" -OU "HostedExUM Integration" -DisplayNumber "+14257273539"

Ok...

When I try this:

New-CsExUmContact -SipAddress "sip:Acme_AA@acme.com" -RegistrarPool "gimlet
.acme.com" -OU "dc=acme,dc=com" -DisplayNumber "+46846501031" -AutoAttenda
nt $True

I get this error:

New-CsExUmContact : Management object not found for identity "dc=competella,dc=com".

Hi, -OU "dc=acme,dc=com" is a domain name, not OU distinguish name, the OU DN should be like as: "ou=redmond,dc=contoso,dc=com".

Thanks!

I created a new OU and used that as a store. Hmmm... the way I tried to do it with just the domain actually worked for OCS 2007...

Lennard. Hi!

I get the same situation,

"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."

but I did not quite undestood what you have done to solve it, if you done...

I had the same issue let me think back to what i did to resolve this....

seems like stale records

 

check your AD for random users in the Users and computers - dont delte the special mailboxes

Luiz: I created a new organizational unit (OU) which I named "Exchange UM Contacts" in my root (DC=acme,DC=com).

Then I used that as an OU for the New-CsExUmContact command: -OU "ou=Exchange UM Contacts,dc=acme,dc=com"

We found a similar issue. We accidently added the contact object to a director. A simple mistake.

I was scratching my head and performing all different types of security changes in AD.  I ended up resolving my issue by running the command via Powershell:

OcsUmUtil.exe /domain:my_domain_name /OU:"desired_OU"
