Hi Guys, We are trying to reset the voicemail pin for a particular user but exchange is reporting this error below everytime we tried to reset the pin. The Operation could not be performed because object 'domain.com/users/user1' on the domain controller 'server.domain.com'. It was performing a command 'get-ummailboxpin -identity domain.com/user/user1'. If we click the "OK" button of the error report, everything is greyed out. Hence, we were unable to reset the pin for the pin. When we also went to the properties of the user's mailbox everything has been greyed out as well hence, we can't modify the user's mailbox properites. What we can't understand is that, it's only happening to a particular user. We can reset the voicemail pin for other users. We've restarted both of our DC and our exchange server hoping to resolve the issue but it didn't. Below are the event logs that we've gathered after the restart of our Exchange Server. _____________________________________________________________________________________________________________________________________________ Event Type: Error Event Source: MSExchange Unified Messaging Event Category: UMCore Event ID: 1138 Date: 7/07/2011 Time: 8:05:26 PM User: N/A Computer: exchange07 Description: The Microsoft Exchange Unified Messaging service could not create and register the Simple Mail Transfer Protocol (SMTP) service principal name (SPN) for the Unified Messaging server.

Hi, You can reset PIN by several way like from OWA,EMC/EMS. Please try to reset it thru powershell and check it. To use the Exchange Management Shell to reset a UM user's PIN Run the following command: Set-UMMailboxPIN -Identity tony@contoso.com If you see any error then please check you are using right account which is having Exchange permission See below URL also for other way to do it. http://office.microsoft.com/en-us/outlook-help/reset-your-unified-messaging-voice-mail-pin-HA010175553.aspx http://technet.microsoft.com/en-us/library/aa998901(EXCHG.80).aspx Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

Hi Anil, Thanks for your reply. I've tried all the different ways to reset the pin however, all of it didn't work. As I've mentioned above, (which I've missed the "could not be found" on the sentence - my apologies) we're are still getting this error. The Operation could not be performed because object 'domain.com/users/user1' could not be found on the domain controller 'server.domain.com'. It was performing a command 'get-ummailboxpin -identity domain.com/user/user1'. May you please explain this error? It is saying that it can't find the object on the domain controller even if the user object is abosolutely on the domain. It can login to the domain and it can send and receive emails. Please help us understand why this is happening and what can we do to resolve this issue. Your help will be much appreciated.

So, you only got one exchange server and one DC in the organization, right? With the same method (EMC or EMS), the PIN codes of other users can be reset For event 1138 and 12011, please try the answer and my suggestions in this thread Please apply Scalable Network Package (SPN) hotfix (KB 950224) on the exchange server Please run ExBPA against the exchange server for health and permission check Possible cause: The “EUM:” proxy address was removed from the problematic user’s SMTP proxy address list Resolution: Add the EUM proxy addresses with the Set-Mailbox cmdlet For example: Set-Mailbox -Identity James@domain.com -EmailAddresses EUM:1111111\;phone-context=DialPlanName; eum:2222222\;phone-context=DialPlanName; SMTP:James@domain.com; smtp:James2@domain.com James Luo Forum Support Please remember to mark the replies as answers if they help and unmark them if they provide no help.

How's the issue currently? Any further information?
