Office 2019 Home & Business 64 bit version on Win10 Pro 64bit with 16GB ram. Closed Outlook many times and opened again. No change. Rebooted system. No change.
Mail host is suddenlink. Have had them for years. Password has not changed in the last year. Opened Outlook today and worked for 4 hours no problem. The password prompt box appeared. Hitting OK will cause it to go away for 3-4 seconds. Then comes back. Hitting cancel does same thing. It starts with the password prompt box now at startup of Outlook and continues until you exit Outlook
I can go to account.suddenlink.net and log into the web version of the email server. So I know my username/password is good.
Suddenlink is POP3. Nothing changed. It just stopped working. Went to Control Panel, Mail (Microsoft Outlook 2016), email accounts, suddenlink configuration, Change, Change account window pops up. Test Account Settings does not work. I am using Office Home & Business 2019 perpetual. I don’t know why the mail icon in Control Panel says 2016.
When I select Test Account Settings from the POP and IMAP Account Settings box, the dialogue box says it gets logged into mail server, but can’t send test email. See first Screenshot. The errors tab says email server rejected login. Verify user name and password. See second screenshot.
I have googled for several hours using different combinations of “Outlook 2019 pop3 suddenlink password”. None of the hits described my situation. Nearly all wanted to coach me through setting up a POP3 account. Tried installing and running Microsoft Support and Recovery Assistant for Office 365. It hung up for 10 minutes. Just killed it.
Following AskWoody’s (former Windows Secrets) recommendation for keeping Updates delayed until after potential issues are resolved with updates. No updates for several weeks now.
