2, 20153 Share 0 0 Over the past several months, I've seen an increased number of Exchange 2013 cases where certain admin users received a 500 owa 500 error exchange 2013 status error when attempting to log in to ECP:
owa error 500 exchange 2010 The first question I ask when I get these specific cases is "Does the admin account have aMicrosoft Forms Based Authentication Service

may know, because of the design of Exchange 2013 - the CAS role simply locates your mailbox, then proxies the request back to your mailbox server - an "anchor mailbox" is used.

You can see evidence of the anchor mailbox when you configure an Outlook profile for an Exchange 2013 mailbox:
Notice the ExchangeGuid is used as the 'Server' in the outlook profile, instead of an actual server name. OK that's great and all, but what does that have to do with thisstatus 500that I'm getting? Well, let's think about it. If the Exchange 2013 CAS needs to know where to proxy a request, but the request is coming from an account that has no mailbox, and thus no ExchangeGuid associated with it, how does Exchange know which mailbox server to proxy?
