I just installed CU6 over SP1 at 8PM uk time 12/09/2014 and for the first time with no errors.
However all databases are mounted byt content index status is unknown.
Get-MailboxDatabaseCopyStatus | Ft Name,contentindexstate, Contentindexerrormessage -Autosize
shows the following error message: Could not find registry value of Index Status for database
And yes checking the key nothing is their (Sophos AV is off)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExchangeServer\v15\Search\IndexStatus
I tried restarting services and recreating the index server to no avail. How on earth do I get contentindex back?
I also have server 2 on a different lan subnet same domain 10mb fibre link, upgrading from sp1 to cu6 but it takes hours to perform the mailbox role transport service, about 3 hours before I finally get an error.
On that server I need to check if the error match's this article [cant link too tired to try and make it! - DiscoverySearchMailbox issue maybe]
On that server the keys exist.
If I stick with server 1 for now does anyone know how to kick the index service back into touch or restore working keys for the registry.
