Outlook cannot connect to PlusNet email server

[#1]

I have just looked up Greenby on Trustpilot. Lost for words; many plusnet customers are very disappointed. Accounts being lost, slow speeds, no customer service etc, etc.

Both are the same, the email address, as are the other plusnet email accounts in Outlook.

Here is the update on uninstalling and reinstalling the problematic plusnet email account.

Reinstalling via Outlook resulted in the same server/password issues as before. Reinstalling via control panel, I added in my original plusnet account log in details in the advanced settings. That seemed to connect with the server but the sending test message triggered this error message "Send test email message:   The server responded: 550 <xxxx@xxxxx.plus.com"

The mail folders for that account are still showing in outlook.

The 550 error message you get suggests a different issue to that of others on the thread. Also, you've not migrated. Please check to see if sending is normal (and no error) in webmail.
