If you facing trouble with your Mail app on your Mac machine and not able to exchange emails, follow these steps to resolve the problem.
Ensure that your computer is connected to the internet. If it is, but the Mail app is no longer sending or receiving email messages, the problem could be at the end of the provider of your email services. Or probably you might have settings that have become outdated. You can check them in the accounts section of your Mail app preferences (Mail > Preferences).
Problem with the mail server or network
The Mail app might suggest that it is not able to connect due to a problem with the mail server and/or network. For example: connection timed out; or too many simultaneous connections.
- If you’re duly connected to the internet and your browser is working just fine but the mail connection timed out, there’s a chance that your email provider could be going through a service outage. In this case you should check its website for a status. Apple’s system status page on its website displays the status of its iCloud Mail among other services. Other providers such as Gmail and Outlook also have status pages on their dedicated websites
- If the error suggests towards the number of simultaneous connections, there might be a possibility that too many of your devices are trying to check your email account at the same time. Try quitting the Mail app on one or more of your other devices and then try it on your Mac
Account appears to be offline
If you’re Apple Support is duly connected to the internet but your email account appears to be offline, chances are that your email settings might not be correct or outdated. You can view your current settings in the Mail application by selecting the Preferences from the Mail menu, then click on Accounts, and then select your email account.
Your Mac device automatically uses the account settings for most of the email providers. You can either use the Mail Settings Lookup function to view those settings, or you can get the required settings directly from your provider. Once received, you can then compare them with the settings in your Mail app preferences.
If mails are arriving with a certain delay
Sometimes, the incoming and/or outgoing emails may taking longer than expected, or they may arrive on one device earlier than arriving on another device.
- The email delivery system is typically scheduled by the email providers, and the delivery time can also be affected by your internet service provider. If you experience significant email delays often, try contacting your email and/or internet service provider(s)
- If the delay occurs when communicating with some particular contacts only, then those people might need to connect with their email or internet service providers
Still can’t send or receive emails?
- Ensure that you have installed the latest software updates on your Macbook Support, especially in cases when the email issue starts occurring right after installing a previous update.
- If your Mac is running on OS X El Capitan or later, you’ll be able to see a status icon and a brief error message in the top right corner of the mail app window, right below the search field. This message can suggest ‘Network Offline’ or ‘Login Failed’. Click on this message to view more details about the problem
- Re-check your connection in the Mail connection doctor app. It may be able to tell more and suggest way to resolve the problem.
