I have an exchange 2003 environment. I am installing new servers for Exchange 2010 to migrate the mailboxes over. I have the CAS and hub transport roles installed. When I try to install the mailbox role I get errors referring to "# upgrade the discovery mailboxes to R5 version, this will fix the RecipientDisplayType property of the discovery mailbox which was wrong in R4. " as well as further down I get "Skipping creating Discovery Search Mailbox because of insufficient permission."
I have looked and found several articles but none seem to fix the issue. Any help? Thanks!
