Exchange 2016 – EAC (ECP) Works But OWA Does Not

KB ID 0001225 


During an Exchange 2010 to Exchange 2016 Migration, I was busy migrating mailboxes into the 2016 mailbox database. I noticed that while the Exchange Admin Center worked fine (I was doing the migration from there!) Outlook Web Access did not. I got a ‘Something Went Wrong” error.
