Question

Delta does't work in AzureChina

test wps 1

in my application, i try to login account with Azure China 21Vianet.
First, i login success with MSAL,
then i try to load data from server with

https://microsoftgraph.chinacloudapi.cn/v1.0/me/mailFolders/microsoft.graph.delta

later,i get 400:Bad Request error, and the message

{
      &#34;error&#34;: {
        &#34;code&#34;: &#34;ErrorInvalidIdMalformed&#34;,
        &#34;message&#34;: &#34;Id is malformed.&#34;,
        &#34;innerError&#34;: {
          &#34;date&#34;: &#34;2020-10-28T11:18:25&#34;,
          &#34;request-id&#34;: &#34;9a6b40af-c64d-4409-b680-6beb6a85d41d&#34;,
          &#34;client-request-id&#34;: &#34;a9e73033-5341-46f0-a9ce-4fbdc1a8fd3e&#34;
        }
      }
    }

Doesn't the AzureChina server support the mailFolders Delta?
Or has another way to make it work?

Thank you for your question!

Has that call ever worked before? If so, when was the last time it worked?
Can you try changing your URL from:
"https://microsoftgraph.chinacloudapi.cn/v1.0/me/mailFolders/microsoft.graph.delta" to "https://graph.microsoft.com/v1.0/me/mailFolders/microsoft.graph.delta"

Looking through the Get mailFolder API documentation and testing this out myself, I found that if I ran the same url you did, I got a 401 error rather than 400:

https://microsoftgraph.chinacloudapi.cn/v1.0/me/mailFolders/microsoft.graph.delta

However, when I changed the URL from "microsoftgraph.chinacloudapi.cn" to "graph.microsoft.com" I was able to make a successful call.

https://graph.microsoft.com/v1.0/me/mailFolders/microsoft.graph.delta

I hope this helps! If you have any other questions, please let me know.
Thank you for your time and patience throughout this issue.

Thank you for your answer!
I had tried this feature with https://graph.microsoft.com/v1.0/me/mailFolders/microsoft.graph.delta, and it worked always.
But it didn't work with "https://microsoftgraph.chinacloudapi.cn/v1.0/me/mailFolders/microsoft.graph.delta"
The "microsoftgraph.chinacloudapi.cn" and "graph.microsoft.com" are from different National clouds: Azure AD China operated by 21Vianet and Azure AD (global service).
National clouds are physically isolated instances of Azure .National clouds are unique and a separate environment from Azure global.
So to solve the problem with 401 error, you should have a Azure AD China operated by 21Vianet account and sign in .
To test graph api in" Azure AD China operated by 21Vianet " , we need to visit the website "https://developer.microsoft.com/zh-cn/graph/graph-explorer-china".
