Owa Error 500 Exchange 2010
The first question I ask when I get these specific cases is "Does http 500 internal server error exchange 2013 ecp the admin account have a mailbox"? In pretty much every case that I can remember, the response is "No". And immediately, microsoft forms based authentication service I know exactly where to look! A little history… As you 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. This anchor mailbox is simply your Exchange GUID, and is used for a number of reasons in Exchange 2013 connectivity. The most obvious, though, are: As mentioned above, so that an Exchange 2013 CAS knows what mailbox server to proxy a request to To prevent the 'Your administrator has made a change so you must restart Outlook'

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?

So how do I fix this? Typically, what I've found is that this is caused by either the database with the system mailbox is unavailable, or some attribute on the system mailbox accou| general In November 2013, Cumulative Update 3 was released for Exchange Server 2013.
