I have a new fresh install of Exchange 2010 SP2. I am trying to create a new DB but I can't mount them. The DB is created but it does not get mounted.
Here is the message that I am getting in the event viewer.
Active Manager failed to mount database MBX01-Editorial on server MBX01.abc.Local. Error: An Active Manager operation failed. Error The database action failed. Error: Operation failed with message: MapiExceptionNotFound: Unable to mount database. (hr=0x8004010f, ec=-2147221233)
We are migrating from Ex 2003 to Ex 2010 and Ex 2003 env is still in place.
As indicated by TechNet I ran the following before the Exchange 2010 installation:
Setup.com /PrepareLegacyExchangePermissions <<domainname>>
All the switches ran successfully.
