Adding Comcast Email to Mac Mail

I've seen an older, very long thread about this issue, and apparently it's still an issue. I've been using Mac Mail for Comcast emails for years without any problems. This worked fine on an older iMac. Now I'm trying to set up my Comcast email on a newer iMac, and I can't. It's not recognizing my email address or password. I've always had the box to allow access to third party programs checked. Xfinity, what is the point of this option if it doesn't freaking work?

I am not going to risk deleting and then adding back my Comcast email, because some posters stated that they couldn't add it back after deleting it. Xfinity should allow customers to make decisions about how to handle their own email and software. Please tell me how to fix this.

Join the club. My MacBook Pro email syncs with the server but my new iPad and iPhone do not. It seems that iOS 26 doesn’t have the choice of pop 3 or imap. I’m guessing that Mac OS Tahoe doesn’t either. I posted for help here yesterday and haven’t  gotten a response yet. I’m calling Apple Care this week hoping I can get help from them. Not sure if I can reach an English speaking Comcast tech to assist. Did you transfer your files from an iCloud backup? Didn’t the email settings download with everything else?

I haven't migrated to the newer iMac yet, for a number of reasons. Not being able to set up Mac Mail didn't help. As I stated, this Mac Mail issue with Xfinity is not new, has been going on for years, and it's ridiculous that they're doing nothing about it.

Now, as of yesterday, not only can I not add my Comcast email account to the newer iMac, as I stated in my original post, I can no longer send emails through Mail. They sit in my outbox and go nowhere. I get this message: “can’t connect to the account “Comcast”. A popup window asks for my password, put the password in and get  "Unable to verify account name or password". In Mail under preferences/server settings, it shows Comcast is "offline". I'm receiving emails, but can't send. I can send through my (android) phone and tablet, and my email on Xfinity's site, but not through Mac Mail.

I just got off the phone with a tech person who couldn't figure out what the problem is. He gave me a number for Xfinity security. I'll call them tomorrow and hope they can help. In the meantime HELLO Xfinity, what is the freaking problem? There are threads going back several years about this. Why can't you fix this? What are we paying your very high rates for?

Sigh ... I'll report back if I get anything useful from security tech help.
