How to Reinstall an Email Address on Macintosh

Occasionally you may find that your email account on your Mac stops working. This can often be easily fixed. Just reinstall an Email Address on Macintosh. Simply disconnect and reconnect the account.

If your email account is not working on one device, but it works on other devices, the fix often involves deleting the account on the device where it is not working, and then reinstalling it.

Generally, email is set up so that it does not actually reside on any of your devices, but rather it is stored in the cloud at the email provider and you can view it from any device that is logged in.

This means your Gmail is being stored on Google’s computers and your Comcast email is being stored on Comcast’s computer.

You will know if this is the case by looking at your email on more than one device (e.g. your computer and your phone). If the email you can see are the same, including any stored in folders, then nothing will be lost by deleting an account and reinstalling it. (If in doubt, come in to SDM and we can help you figure that out.)
