hello,
I am migrating from Exchange 2010 to 2013, everything went smoothly till migration step.
Anytime I start a new migration batch I get error "A valid Migration mailbox could not be found for this organization".
Tried these workarounds:
-Enable-Mailbox -Arbitration -Identity "Migration.8f3e7716-2011-43e4-96b1-aba62d229136"
Getting error "The object is read-only because it was created in a version of Exchange later than 1.1 (15.0.0.0)". Current supported version is 1.0 (14.0.0.0)
didn't run : -Set-Mailbox"Migration.8f3e7716-2011-43e4-96b1-aba62d229136" -Arbitration –Management:$true
because of previous error.
Any suggestion would be great
