Exchange Owa Internal Server Error

2, 20153 0 0 0 Over the past several months, I've seen an increased number of Exchange 2013 cases where certain admin users received a 500 status error when attempting to log in to ECP:
The exchange 2010 owa 500 internal server error first question I ask when I get these specific cases is "Does the admin exchange 2013 owa 500 internal server error account have a mailbox"? In pretty much every case that I can remember, the response is "No". And immediately, I knowExchange 2013 Owa Http 500 Internal Server Error
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' message that you get when http 500 internal server error exchange 2013 ecp a mailbox is moved to a different site. 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? In instances like this, Exchange 2013 uses the ExchangeGuid of system mailboxes to determine where to proxy the requests. In this specific scenario, Exchange uses the system mailbox SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c} Note: When pulling up the system mailbox(es) using Get-Mailbox you must specify the -Arbitration parameter or the command will not work. 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 account has become corrupt or is missing.

Users are able to connect to their mailboxes through outlook and smartphones correctly. When I attempt to login to the owa website, it brings up the login page, enter my username and password, and it immediately goes to a "The website cannot display the page" screen. The error is for "HTTP 500 Internal Server Error". I have already tried resetting my virtual directory for internal server error owa with the same error. I don't know what to do to fix this problem.
