I have had Exchange 2010 SP1 (latest updates) running since November of 2010. I am attempting to diagnose an issue where Outlook 2003 produces several of the "Outlook is trying to retrieve data from the Exchange server..." messages per day, and ran across a couple of oddities using the Best Practices Analyzer.
1 - Unknown schemea extension version
"The Exchange schema extensions are from an unknown version. Schema version detected is 14726."
This link: http://technet.microsoft.com/en-us/library/aa995628(EXCHG.80).aspx
suggests running "setup.exe /PrepareSchema" for 2007, however there is no mention of Exchange 2010. Am I safe to do this? Will it cause me any problems with an already established 2008 AD and Exchange 2010 envrionment?
2 - Unrecognized Exchange signature
"Active Directory domain 'THEKITCHENINC' has an unrecognized Exchange signature. Current DomainPrep version: 13040."
This link: http://technet.microsoft.com/en-us/library/aa997081(EXCHG.80).aspx
suggests that I need to run PrepareDomain for Exchange Server 2010 and the DomainPrep version is listed as shown in this grab from the article itself: "For Exchange Server 2010 Service Pack 1 (SP1), the objectVersion value is 13040"
Ultimately, my issue here is that these two things would have had to be done during the initial setup of Exchange 2010, and I am certain that they have been performed. It is just a simple case of "I need to run it again", or is there something I am missing? What repurcussions will result from doing this procedure again? Recommendations are welcome!
