I have inherited a bit of a disaster. The Exchange 2007 Server (running on Server 2003 64bit STD) is not accepting any updates. Took a look at the Exchange Setup log and it states the last install (update) was Roll-Up 1 bringing the version up from 240 to 263. Consultants tried to install Roll-up 6 & 7. They both installed per their install log but ESM revision is is still Roll-Up and none of the "Roll-Ups" can be seen in the Add/Remove category of Exchange. Yes, I did check the box to view updates. Also, ran the command line in powershell to confirm the revision is what was stated on ESM GUI.
I have two options:
1. Find a fix so updates can be applied
2. Rebuild it
I am leaning towards the second options as a quick fix. I only say this because the consultants have worked on this issue for over three months (with Microsoft) and found not solution.
So, question is.... I have a full backup of Information Store. If I was going to reload the OS and E2007 app, what would be the best way (with same machine)? I have never done a restore of E2007 and was hoping to find someone who has and knows what to do here.
