Every technical process tends to have some issues. When it comes to email, the issues are most common and very easy to resolve. On getting a mac.com email login issue, all you have to do is check what went wrong. Start by checking your login credentials if you are unable to login to your email id. The username and passwords are highly case sensitive so make sure you are entering the exact credentials. Another important thing to check is the server and port settings. Check the incoming server settings and the outgoing server setting as it’s the main reason why you might not be able to send/ receive emails with your email account. Depending on the protocol you are using, whether it’s POP or IMAP, check your port settings. In case the issue with your mac.com persists, connect with the experts immediately.
