Using classic Outlook for Windows in business environments
I have had the same problem but did not notice it because I also use an alternate email address (not Charter) that was receiving emails. March 5, 2024, was when I noticed the broken connection with the same error message that you have. Any fix? From what I've seen in other posts, the problem is with MicroSoft. I noticed that the iPhone version of Outlook connects fine, but the Windows 11 desktop version does not.
I switched to the new Outlook on my desktop last year and it worked fine (though I didn't really like its interface) until March 3 when I could no longer receive or send. After several days and attempts at fixes, I deleted the account and tried to set it up again in the new Outlook. I received something like a 'password not correct or may need app password' message. My Apple devices continued to receive email fine. Came to this site and learned that the new Outlook appeared to be the issue so found and reloaded the old Outlook and was able to add my Spectrum account (I have an old RoadRunner email addy from TimeWarner days) and everything reloaded fine, so am happy with that!
Please Microsoft - continue to support the classic Outlook version!
