I am trying to add Claude for Outlook, I downloaded it and when I say open nothing happens. Is there something I need to do once I get the add-in?

    Hi Kevin Gahwyler

    There is typically no additional setup steps required after installing the Claude for Outlook add-in, once it’s added to your Microsoft 365 account, it should appear automatically in Outlook.

    I also tested this on Outlook Classic Version 2604 (Build 19929.20172), and it worked as expected. After adding the Claude add-in, it appeared automatically without any further configuration.

    Because of that, the behavior you’re seeing is unexpected.

    Could you confirm when you open New Outlook or Outlook on the web, do you see the Claude add-in under Home > More Apps?

    If it appears there, that will confirm the add-in is installed correctly and help narrow the issue down to Classic Outlook specifically.
