How To Sync Email Across Devices

Dear Computer Lady,

I love your newsletter and have learned so much! I’m hoping that you can help me with this question.

I would like to link my iPad, iPhone, and Dell Windows computer so that when I delete an email on one device it’s deleted on all of them.

Is there a way to do this? I use Comcast for my email.

Thank you so much for all you do! Judy

Dear Judy,

In order to sync your email across your iPad, iPhone and Windows computer, you need to set it up to use IMAP servers instead of POP servers. Let me explain:

The original email protocol, created in 1984 is POP, which stands for Post Office Protocol. POP downloads your email messages from a remote server and stores them on your computer or other device.

IMAP stands for Internet Message Access Protocol. It was created in 1986. IMAP leaves your email messages on the remote server, and just stores a temporary copy of them on your device. Each time you connect to the server, it syncs your messages so anything you delete on your computer, is deleted on the server, anything you move from one folder to another on your computer is also moved on the server.

Both of these protocols allow you to read your emails using an app or program installed on your devices.

My guess is that you have your comcast email set up to use POP instead of IMAP. Switching to IMAP will result in your email working the way you want it to.

You might have to contact Comcast for directions on exactly how to do this, or switch to something like Gmail, which you can use with the Gmail app on your phone and tablet, and Gmail website on your computer.
