teamSiteDomain variable is not replaced when SPFX app is loaded in Outlook

[mdissel]

We load our SPFX app in the latest Outlook client version 2307 (build 16626.20000 Beta channel)

The teams manifest file contains the {teamSiteDomain} variable that is dynamically replaced by MS Teams with the correct sharepoint tenant url. But this variable is not replaced when the APP is loaded in the latest outlook client.

@sayali-MSFT How can I add my SPFX / Teams fullpage app to OWA so that users can add the application to the left panel in OWA?

@mdissel -Please have look into this sample for reference-https://github.com/OfficeDev/Microsoft-Teams-Samples/tree/main/samples/msgext-link-unfurling/csharp#outlook-on-the-web

@sayali-MSFT I've added the TeamsSPFxApp.zip to the sppkg package, the app can be added to the left navigation panel in MS Teams, but is not available in OWA (or the new Outlook). See screenshot. The teams manifest.json is on verson 1.16

If I look in the app catalog in SharePoint, I see that the app is only available for SharePoint and Teams.

@mdissel -Could you please try with the below sample once-https://learn.microsoft.com/en-us/microsoftteams/platform/sbs-gs-spfx?tabs=vscode%2Cviscode&tutorial-step=1

@sayali-MSFT But see my screenshot from Outlook Web Access (outlook.office365.com, but the same for outlook.office.com) , there's no option to add an app, so I don't think it has any to do with my app registration.

Hi there, could it be that the problem is fixed, but the variable is not consistently substituted?

When i Add the Epona365 web app, restart Outlook (classic) the APP will work for a while. At some point the proper URL is no longer inserted in the APP and it stops working. See the image below:

When you choose Pop-Out APP, this will work fine, so it must be the Outlook runtime loading of the APP

Can you please re-open this request from Marco Dissel?

I’m experiencing the same problem as @mdissel. This issue is not only occurring with the Outlook desktop client, but also with M365 and the Outlook 365 mobile app on both Android and iOS.

I’m attaching a screenshot that displays the network call being made by the Outlook desktop client. I’ve also included a screenshot of the M365 app for Android, showing the call it’s making. As you can see in both screenshots, the URL is not being replaced. However, the app functions correctly when I use it on Outlook Web.
