Hello 6e0a867595f9 

Thanks for writing to us back.

I'm not sure why the /autodiscover/metadata/json/1 endpoint is not documented on that page but it's mentioned on this page about validating the identity token which we deal with in Jira Cloud for Outlook add-in.

Unfortunately, we do not control which Autodiscover URL to use from our side. The URL is provided securely in the identity token by Outlook and we read the URL from there.

I'd suggest you reach out to Microsoft support if you have any other questions about Autodiscover URL. They can provide more information about Autodiscover URLs and how to set them up for Outlook add-ins to work properly. Please let me know if you had a chance to resolve this issue on your side.

Hello 

According the official documentation of Microsoft for our Version Exchange 16 this Autodiscover Link is the following : https://learn.microsoft.com/en-us/exchange/architecture/client-access/autodiscover?view=exchserver-2019

and not the one that you are sharing

Hello,

Unfortunately, https://autodiscover.leyton.com/Autodiscover/Autodiscover.xml won't work for us, we don't control which URL to use. The URL is coming from the Exchange identity token which we get from the Outlook client, we parse that URL from the token and then send a request to that URL to get the public key. Here's more about the token validation.

The URL that the Exchange Identity token contains for your Exchange server is https://exchange.leyton.com:443/autodiscover/metadata/json/1.

The payload should be pretty similar to this one https://outlook.office365.com/autodiscover/metadata/json/1. The URL should also respond with 200 HTTP status code.

Hello

we have already seen with our network administrator the only address to use is the one we have already sent.
https://autodiscover.leyton.com/Autodiscover/Autodiscover.xml
Have you been able to test it?

Hi 6e0a867595f9 

The URL that should be publicly accessible is https://exchange.leyton.com:443/autodiscover/metadata/json/1. When I open it in the browser, I see the login page, so it's not accessible.

Could you please talk to your network administrator so they could open this URL? Once it's done, the integration should start working.

Hello

Please note that our problem is not yet solved we were waiting for the answer of our network administrator who was on vacation.

Our Autodiscover address is:

https://autodiscover.leyton.com/Autodiscover/Autodiscover.xml

thanks in advance

Thank you, 6e0a867595f9, this helps. I verified it on our side, and seems like it doesn't work because of the misconfiguration of your Exchange server.

The context of the problem

Here are some technical details of what's going on.

In order to secure the connections between Outlook and Jira Cloud for Outlook add-in, Outlook provides us with a token that we use to sign all requests coming to our server. This token allows us to verify that the request is coming from you and not some attacker. In order to verify this token on our side, we need to load a public key available at your Exchange server. The URL we use to download that public key is also known as Autodiscover URL. More details about token validation here.

The reason the add-in doesn't work for you is that the Autodiscover URL of your Exchange server is not publically available and for that reason, we can't download the public key and verify the token.

How to fix the problem?

To make it work, your admins who manage the Exchange server, should make the Autodiscover URL either public or allow access to it from the IP addresses listed on this page (more specifically https://ip-ranges.atlassian.com).

Because this issue is publically available, I can't share the exact URL which is blocked, otherwise I'd expose your company's site. The structure of the URL is the following:

https://exchange.<your-company-domain>:443/autodiscover/metadata/json/1 

Here are more information about Autodiscover feature of Exchange server for your admins:

• Autodiscover for Exchange
• Autodiscover service in Exchange Server

Let me know if that helps.
