Owa 500 Internal Error

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 status error when attempting to log
Owa Error 500 Exchange 2010
in to ECP:
The first question I ask when I get microsoft forms based authentication service these specific cases is "Does the admin account have a mailbox"? In pretty much every case that I can microsoft forms based authentication service exchange 2013 remember, the response is "No". And immediately, I know exactly where to look! A little history… As you may know, because of the design of Exchange 2013 - the CAS roleHttp 500 Internal Server Error Exchange 2013 Ecp
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 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.

| general In November 2013, Cumulative Update 3 was released for Exchange Server 2013. This update resolved many issues with Exchange Server and proved to be advantageous for both Administrator and clients. However, the http://www.blog.edbtopst.org/ecp-and-owa-login-fails-with-error-500-in-exchange-2013.html users can encounter various issues with the Cumulative Updates. Issues With Cumulative Updates of Exchange Server 2013 With Cumulative or some other updates, the users can come across some difficulties after the installation. Some of the issues include: Powershell shortcuts https://ril3y.wordpress.com/2014/03/25/exchange-2013-owa-and-ecp-logins-fail-with-500-error/ get omitted.

Let’s now move to the reason due to which this error occurs. Cause Of The Error 500 in Exchange 2013 The main reason behind the log in failure of OWA and ECP is the mismatch of canary tokens between the client and server A canary is usually a secret token between client and Server in OWA, ECP or some other web services that is stored in the cookie collection of the browser and gets submitted with various requests which the browser sends. For each request the value of GUID stored in the URL is compared with the one stored in session state. If the value of GUID stored in these location do not match or if the value of GUID is lost from the URL, the request becomes malicious and it is blocked. As a result of it, the users will encounter “http error message 500: Internal Server Error” and the Server will come across an unexpected condition that stops it from executing the request. Functioning Of Canary Tokens In Normal Condition And At The Time Of Error Generation As mentioned above that the mismatch of canary tokens between the client and the Server is responsible for the generation of error 500. Let’s have a practical look on the func
