New Outlook 365 supports IMAP only, POP3 not available




Microsoft’s new Outlook for Windows has removed support for POP3 (Post Office Protocol version 3), leaving many users seeking alternatives. This change could be a challenge for those who prefer storing emails locally instead of on the server. Here’s what you need to know and how to manage the transition.

POP3 has long been favored by users for its ability to download emails to a local device, freeing up server space and preventing storage overloads. The shift to IMAP in the new Outlook means emails will stay on the server, consuming storage and potentially causing performance issues. This could especially affect users with limited storage plans, leading to undelivered emails or extra costs for additional storage.

Security Implications:
POP3 also offers better security by storing emails locally, reducing exposure to cyber threats. With IMAP, emails are constantly synced with the server, making them more vulnerable to hacking and phishing attacks.

Alternatives for POP3 Users
If you’re relying on POP3, here are a few alternatives to consider:

1. Mozilla Thunderbird
A free, customizable email client that fully supports POP3 and offers robust local storage options.

2. Older Outlook Versions
Versions like Outlook 2013 and 2016 still support POP. However, they may lack security updates, so use them with caution.

Conclusion
Until Microsoft offers POP3 support again, these alternatives will help you continue working with your preferred setup.
