Delete Offline Address Book created with newer version of Exchange

A few weeks ago, I upgraded to Exchange 2012 from 2007. Shortly thereafter, we found that some of our applications were not compatible and decided to move to Exchange 2010 instead.

The migration to 2010 went smoothly, and all mailboxes were moved over to the new Ex2010 server without incident.

Now, however, I am attempting to uninstall Ex2007 and am encountering errors due to an existing Offline Address Book. The OAB in question was created by Exchange 2012 ("Default Offline Address Book (Ex2012)") and is still set as the default, even though Ex2012 has already been uninstalled.

I have created a new OAB, but am unable to set it as the default. I receive the error "The propery 'IsDefault' is on a read-only object and can't be modified". I receive the same error whether I attempt to remove the OAB via the Console or Shell.

When I attempt to delete that OAB, I receive the error "Default Offline Address Book (Ex2012) was created by a newer version of Exchange. Exchange version 15.0.0.0 or later is necessary to manage this object."

I tried installing Ex2012 Management Tools on another machine and using that console to remove the OAB, but receive the same error.

Is there any way I can force remove this OAB or set the newly created OAB as the default?

Any suggestions would be greatly appreciated.

I guess you are referring to Ex 2013. Without seeing the environment i wont suggest any R&D. If you have MS support, open up a case with them and let them have a look. I guess you might end up using adsitedit tool for this task.

Yes, sorry I meant Ex2013.

I do not have MS Support, unfortunately -- we're a very small organization.

I suspect ADSI Edit will probably come into play, but I'm extremely wary of getting into that without some guidance.

All Exchange related settings are store under configuration partition. You can explore there, however if you are not confident using adsiedit tool, don't use it. If exchange 2007 is not causing any issue, leave it as it is.

Ex2007 is on a SBS 2008 server. My new Server 2012 Essentials is in migration mode, so I need to get Ex2007 uninstalled and SBS 2008 demoted and taken offline very soon to prevent it from shutting down every hour.

Either way, there are still numerous references to the Ex2007 server floating around -- It needs to be uninstalled so we can complete this migration and repurpose that server.

Thanks again.

Would there be any harm in reinstalling Ex2013 on another server, using that to remove the OAB, then uninstalling Ex2013?

You can try it. Reinstall old server with recover server switch.

I was able to install Ex2013 on a new server, then use its shell to remove the OAB created by the previous Ex2013 install.

Once that OAB was removed, I was able to use the Ex2012 console to create a new OAB and successfully mark it as default.

Resolved problem by reinstalling Exchange 2013, then using the Ex2013 shell to remove the problem OAB.

Can I install just the management tools? Installing full exchange 2013 seems a bit excessive...
