@ismrahi Thanks for reporting. Can you please also share if you see any errors in console

Thanks for reply. I have already added console errors in Useful logs section. Let me know if you need any further logs.

[mmanjaree-msft]

@ismrahi What I am looking for is errors in console. If there are any error coming from office js , please share that. Also is the add-in working in outlook web?

[ismrahi]

@mmanjaree-msft : Some console errors are like below even before launching plugin on sidebar.

This document requires 'TrustedScriptURL' assignment

Plugin also not working outlook web!

@ismrahi Could you please confirm if you are able to launch other-addins?

[ismrahi]

@Swathy-Mothilal : we are not using any custom web add-ins which build using outlook js. Some standard apps seems o be working fine with new outlook version.

@ismrahi Is this the real source location that your addin is trying to load or its just some dummy site?
https://examplecompany.com/sap/bc/bsp/sap/Z_PLUG/taskpane.html?sap-client=030

Can you share the actual manifest by creating a private repository and adding us to the same.

[ismrahi]

@rkpathak : That is dummy site. We are doing authentication using SAML, could be that issue??

So in manifest file we added AppDomains as https://login.microsoftonline.com and our custom domain.

Thanks

[ismrahi]

@rkpathak : any update on this?

[rkpathak]

@ismrahi Please share the actual manifest that is causing problem. You can upload it to a private repository and add us there.

[ismrahi]

@rkpathak I have shared the original manifest file with you as requested. Thanks

[rkpathak]

@ismrahi How you shared the manifest, I cant find it? Can you share the link or create a private repo and add @exextoc to it.

[ismrahi]

I have added both user profiles and below is the status

We conducted a further analysis and discovered that the issue lies with SAML authentication (using Microsoft Entra ID) for our app.

When using SSO with certificates, the add-in form appears correctly on the right task pane. Additionally, we noticed in the developer tools that with SAML, there are numerous redirects and authentication loops.

I have shared the .HAR file from a private repository for your review.

Here is the screenshot from the developer tools:

any update on this? Thanks

@JuaneloJuanelo, can you help with the right contact here for authentication.

[ismrahi]

are there any other ways where we can get trace/logs besides F12 dev tools? Local PC or office 365?

We attempted those steps but did not find any useful information. Could you please share any registry settings or other methods we can activate to obtain extended logs?
