To receive current mail in Outlook, you do not necessarily need the Outlook mobile app on your phone. Outlook can be used on your PC to access your email, including Hotmail. However, if you are experiencing issues with not receiving current mail, it may be related to the version of Outlook you are using on your PC or the configuration of your email account.
To check your version of Outlook, you can usually find it by going to the File menu, selecting Office Account, and looking for the version information there. If your version is outdated, consider updating it to the latest version to ensure compatibility and access to the latest features.
If you are using an IMAP account and are not receiving emails, it could also be due to issues with the IMAP server or settings. In such cases, you may want to check your account settings or contact your email provider for assistance.
