Outlook Add-In still not working after following setup instructions

Hi Community,

I’ve been working on resolving the Outlook Add-in issue related to the February 17, 2025 change (legacy authentication tokens being turned off). I have carefully followed all the steps outlined in the knowledge base and community posts, including:

• How to resolve the issue when users are unable to sign in to Acumatica Add-In for New Outlook on Windows

• Known issue: Starting 17th February, 2025, Acumatica Outlook Add-in may stop working

Steps I’ve already completed:

• Upgraded Acumatica instance to the correct supported build.

• Enabled OpenID Connect in Acumatica.

• Registered the application in Microsoft Entra with redirect URI, API scopes, and permissions.

• Created the OpenID Provider in Acumatica with the correct Tenant ID, Client ID, and Client Secret.

• Installed the new Outlook Add-in using the updated manifest.

Problem: Despite all of this, the add-in still does not work. I either get [describe your exact error: blank screen, token error, redirect loop, etc.].

Question: Has anyone else experienced this even after following the official instructions? Is there an additional configuration step or workaround that might resolve this?

Any guidance would be appreciated.
