Hi there, this is what happened: - we currently using exch 2007 on Server 2008, this was migrated from exch 2003 a while ago - we also have exch 2010 in our domain (different server) but still using the 2007 as our main one (haven't migrated) - I created a new user and a new email address policy as a test, I created the new user with the [company] field as "test company". this also created the email address based on our existing default email address policy (probably carried over from the old exch 2003). then create the new email address policy with the filter recipient is in a company set as "test company" (this returns that 1 user when previewed). add a new email address format and choose to run immediately. it says success but with a warning ... Warning: Failed to update recipient "domain.com/OU/Test User". The following exception occurred: Exchange Server 2007 exch.domain.com returned an error -2147023286 from the Address List Service. Exchange Management Shell command completed: update-EmailAddressPolicy -Identity 'test email policy' this didn't make any changes to its email address. Any idea?Andrew P.

Restart the MS Exchange System Attendant Service and check. Post the update.Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com

thanks for the reply, but, since this is a live server, will there be any "side-effect"?Andrew P.

NO..and i am sure it's not going to take more than few seconds to restart the service. When you talk about the side-effect, the mail flow won't be disturbed.Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com

I've restarted the said service, but it's still no good. the same error message appears.Andrew P.

How many domain controllers you have? Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com

there' are 2. none of them have exchange installed. Andrew P.

You need to reboot those domain controllers one after another. Would that be possible? Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com

ouch! not possible. could you explain why I need to restart it/them?Andrew P.

I remember i had this issue once, in my case issue got resolved by restarting the DC's. could be an AD Replication issue of some type. Hoping this will fix your issue as well.Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com

well, I suspect that the issue was with the address list of some sot since this new user has just been created. maybe you know of some service that can be run to force the replication or whatever?Andrew P.

Hi I find similar case http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/c649e8c2-b69b-4a23-8303-08d78a6c8e4b Can you read my colleague’s advice and check your server? This could be as simple as a need to restart both DCs in the local AD Site or it could be an AD Replication issue of some type.

got it. due to the presence of Exchange 2010, this needs to be run from the exch 2010 server. dunno why.Andrew P.

You cannot be serious............... Were you running it from 2003? OMG....Anyways...you got it fixed that's important...cause i was thinking that you are running it from 2010. It has to be run from 2010. Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com
