Auth.owa Internal Server Error
Contents |
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 exchange 2013 ecp http 500 internal server error attempting to log in to ECP:
The first question I exchange 2013 owa http 500 internal server error ask when I get these specific cases is "Does the admin account have a mailbox"? In pretty much exchange 2013 ecp 500 unexpected error every case that I can remember, the response is "No". And immediately, I know exactly where to look! A little history… As you may know, because of the designExchange 2013 Ecp Error 500
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 exchange 2016 ecp error 500 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-Mailbo| general In November 2013, Cumulative Update 3 was released for Exchange Server 2013. This update exchange 2016 ecp 500 unexpected error resolved many issues with Exchange Server and proved to be advantageous for

If case of such scenarios either of the following errors will be generated: Event ID: 4 & 1309 : caused due to ASP.net Error 500: caused due to login failure of OWA or ECP However, both the above mentioned errors can prevail in Exchange Server environment but we will focus on "ECP And OWA Logins Fail With Error 500 in Exchange 2013″ . 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 th

The issue is that if you have the servers offline and you complete the domain name change your old servers don't get the new changes. This ended up resulting on us being unable to bring that server back to fully functional status and losing our ability to manage our Exchange Hybrid configuration. Long story short I needed a new server to manage Exchange Online. I decided to grab a new VM and deploy Exchange Server 2013 CU2 but I encountered a blank HTTP 500 page after providing my credentials to enter Exchange Server 2013 ECP. Below is a brief story of this long saga: As many of you probably know by now, HTTP 500 error messages are generally attributed to either Certificate misconfiguration or Authentication misconfiguration of OWA and ECP. Certificate problems arise when the certificates you are using on the backend are corrupted or there might be another issue like validation, etc. This generally can be easily resolved by assigning a new certificate to your Exchange WebServer. You can do this via Exchange Shell or the not so recommended way: directly on IIS. Authentication problems arise when you are not using the same authentication methods on your front and backend Exchange WebSites. The default recommended approach is Forms Based Authentication. The recommendation at this point is to use the Exchange Management Shell to establish both the OWA and ECP site
