The “Copilot GPT” gave this answer that seems reasonable.
“The new Outlook for Windows currently lacks support for IMAP accounts. This means that you cannot add email accounts from providers like Yahoo!, iCloud, or others that use IMAP protocols to the new Outlook app. However, there’s good news! The Outlook team is actively working to enhance the app’s capabilities, including adding support for more account types, including IMAP accounts. While they haven’t announced a specific timeline, they are listening to user feedback and prioritizing requested features^1^. In the meantime, here are some steps you can take:
- Use Classic Outlook: You can continue using the classic Outlook for Windows app to access your IMAP account.
- Web Access: Access your email provider’s website via a web browser.
- Toggle Between Apps: You can switch back and forth between the new and classic Outlook for Windows apps using the toggle switch at the top-right corner of the window.
Stay tuned for updates on the new Outlook for Windows development, and soon you’ll be able to manage your IMAP accounts seamlessly! 📧🔍”
