Hi all,

I am developing an outlook add-in that supports OWA, desktop, IOS and android. I am using the following graph API to get the mail item.

[/v1.0/users/testuser@testdev.onmicrosoft.com/messages/${mailItemId}]

This works on almost all the tenants that I have tested but there is one particular tenant that recently migrated mailbox to exchange online from on-premises exchange. That tenant is only having the following issue.

When I am running the add-in on email on outlook desktop, this graph API call works fine but when I run the add-in on IOS device on the same email I ran on the desktop then this graph call fails and gives the following error.

Code: ErrorAccessDenied

Message: Access is denied. Check credentials and try again. The store ID provided isn’t an ID of an item.

When add-in runs on OWA or desktop I convert mail item id to REST-formatted using Office.context.mailbox.convertToRestId method before making the graph API call but in IOS or Android environment I don’t convert the mail item id because, In Outlook Mobile, the value returned by Office.context.mailbox.item.itemId is a REST-formatted ID and can be used as-is. I am doing that conversion as follows.

function getItemRestId() {
  if (Office.context.mailbox.diagnostics.hostName === 'OutlookIOS'  ||     Office.context.mailbox.diagnostics.hostName === 'OutlookAndroid') {
    // itemId is already REST-formatted.
    return Office.context.mailbox.item.itemId;
  } else {
    // Convert to an item ID for API v2.0.
    return Office.context.mailbox.convertToRestId(
      Office.context.mailbox.item.itemId,
      Office.MailboxEnums.RestVersion.v2_0
    );
  }
}

The following one is the graph call that is made by IOS device, and it doesn’t work.

 

GET [/v1.0/users/diluka@testdev.onmicrosoft.com/messages/AAkALgAAAAAAHYQDEapmEc2byACqAC-EWg0ASnkxz0CXRky-Oh3HtJRmdAAAmwAojQAA]

 

The following one is the graph call that is made by outlook desktop, and it works fine.

 

GET [/v1.0/users/Diluka@testdev.onmicrosoft.com/messages/AAMkADRkNTM0MWZkLTc2NTItNGI2Ny1iOWZiLTFiNDM5ZmIzOTM5ZgBGAAAAAAAftAEVwxU3RaepYBocX1JuBwDnWRi5bPz9Q7jQYCDNVSj8AAAAAAEMAABKeTHPQJdGTL86Hce0lGZ0AAChIRN0AAA=]

 

**** These both graph calls referring the same email ****

 

Can anyone help with this issue?
