Just wondering if any of you have had any upgrade issues with this particular upgrade? I run a single Exchange 2k3 server, SP2 and when I ran this upgrade, my queues immediately started backing up with everything queuing up in the "Messages awaiting directory lookup" queue. I troubleshot for a long time, and found no issues in my AD setup or DNS setup that would cause this. I ended up doing a complete removal of SMSME and I still could not get email to process. It was easier and quicker to restore from backup than to continue troubleshooting, but now I am gunshy about continuing to use SMSME on my server. As soon as I recovered from backup email processed without any errors or queueing. Everything on my end points to the upgrade, but I see no indication on these forums that anyone else is having issues.
Thanks for any feedback.
