Switch Comcast pop email to IMAP

I'm sorry I could not get back on last night to help you. You can try and force the mail to error out. Delete the mail account again as I said, then when you go to add it back, enter an incorrect password. It will not verify. It will bring you to a page where you select POP or IMAP. You have to be sure you are in a location where they support IMAP, but I'm pretty sure they do all over. It has been a while since they switched. Now, after you select IMAP, go ahead and enter your correct username and password, then you will have to fill in the rest of the information as you continue. I'm not sure if the Port differences between what I have and what QuickTimeKirk provided makes a difference, but you can try both if necessary.

Incoming Mail Server

Host Name: imap.comcast.net

I probably shouldn’t butt in now, but it was very simple to convert my Comcast POP account to IMAP. I did this for my wife and for myself right on our devices. It’s been a few years but it was very simple.

The short explanation is that you add a “new” Comcast account and after everything is set up, you delete the POP account. I believe that Comcast mail now defaults to IMAP when setting up a new account.

I used these instructions from Xfinity. The only thing that I did differently was to not use Comcast Notes so I did not enable Notes in the settings.

ChrisJ4203 may know something that I don’t know, but I’m just offering this as an easy alternative to try.

Thanks Demo. You are right, it should have defaulted to IMAP, however the OP stated that when they added it back, it added back as a POP account. The "fix" that I provided will force it to the page that allows you to select POP or IMAP, which does not appear by default anymore. It should still be as easy as you stated, but something wasn't going right, that is for sure.

I’m glad to hear that Comcast was able to help you and that your IMAP email account is up and running now.

Delete the account, power cycle the iPhone off and back on again, then add the account back. It should pick it up as an IMAP account. If not, come back and we can try something else.

Ask Comcast for help.

I’m sorry, I missed that. I glossed over the thread and didn’t read all of the details as I should have.

Glad you were able to get it all straightened out. Enjoy your Apple devices.
