IMAP connection error INVALIDCREDENTIALS
Hi MVdM, INVALIDCREDENTIALS usually means the IMAP server is rejecting the login method, not necessarily that the password is typed wrong. Check whether Easyhost requires an app password, SSL/TLS on the right port, or username as the full email address. Also test the same mailbox in classic Outlook or Thunderbird. If it works there but not in new Outlook or Outlook.com, the provider may not accept Microsoft's cloud-based IMAP connection flow.
Hi, I experienced the same issue myself with only one cPanel IMAP email account after changing its password. It does not work with any of the new Outlook apps tested across several devices, but it works in other email clients such as Outlook Classic and Thunderbird. The strange thing is new outlook app accepts other email accounts that are using the same domain and the server. I suspect that something is wrong with outlook cloud and this happened after changing the email password(password is correct as tested with webmail, outlook classic and thunderbird).
