I am trying to install Exchange 2010 in an Exchange 2013 environment which was migrated from Exchange 2007 earlier.
Exchange 2010 sp1 Mailbox and Hub roles installed fine however I cannot install the CAS role. Saw some references to change the OAB to a non exchange 2013 version - however that is the only version we have = OAB 2013.
This is the error I get:-
Error:
The following error was generated when "$error.Clear();
get-OfflineAddressBook -DomainController $RoleDomainController | where { $_.IsDefault } | Enable-OabWebDistribution
" was run: "The object is read-only because it was created in a version of Exchange later than Exchange 0.20 (15.0.0.0). Current supported version is 0.10 (14.0.100.0).".
The object is read-only because it was created in a version of Exchange later than Exchange 0.20 (15.0.0.0). Current supported version is 0.10 (14.0.100.0).
