Answer 2

Hello, thank you for reaching out to Microsoft Q&A.

To better understand the issue, I would like to know the following information:

1. Are you having trouble adding your email account back to the Outlook Classic app, or is the Outlook Classic application itself not working or reinstalling?
2. Have you tried creating a new Outlook profile to see if that resolves the issue?
3. What error message or behavior do you see when you try to reinstall Outlook Classic or add your account to the Outlook app again?

To get classic Outlook working again and reinstall it on Windows, use the official classic Outlook installer instead of relying on the “go back to classic” button or Store-only options.

1. Install or reinstall classic Outlook
   1. Open the article "Install or reinstall classic Outlook on a Windows PC" in a browser: https://support.microsoft.com/office/install-or-reinstall-classic-outlook-on-a-windows-pc-5c94902b-31a5-4274-abb0-b07f4661edf5
   2. Scroll to the "Select a language and download classic Outlook" section.
   3. In the table, find the preferred language (for example, "English (United Kingdom)", "French", "German", etc.).
   4. Select the corresponding Download link (for example, for English (United Kingdom): Download next to English (United Kingdom) / en-gb). This downloads the classic Outlook installer.
   5. Run the downloaded installer and follow the prompts to complete installation.
   If preferred, classic Outlook can also be installed from the Microsoft Store using the Store link in the same article ("Tip: You can also try installing classic Outlook from the Microsoft Store").
2. If the “go back to classic Outlook” button is not working If new Outlook is installed and the in-app "go back to classic Outlook" button just closes the app and does not install classic Outlook, use the workaround:
   1. Open the article "Go back to classic Outlook button not working correctly in new Outlook".
   2. Use the store install link in that article ("You can't open classic Outlook on a new Windows PC") to open classic Outlook in Microsoft Store.
   3. Install classic Outlook from the Store page that opens. The Store will match the language for the region automatically.
3. If using a work or school account If classic Outlook still cannot be installed or activated with a work or school account after using the above installers, contact the organization’s IT admin for assistance, as suggested in the classic Outlook install article.

Once classic Outlook is reinstalled, configure the email account again and allow it to resync mail. If mail was “dropped” due to using new Outlook (which does not use local PST files in the same way), ensure the account is added back in classic Outlook so that messages are downloaded again from the mail server.
