Emails aren't sent or received - emails moved to outbox - open emails to see what's wrong

Same issue with my S10....Comcast needs to fix this issue.  Uninstallingand reinstalling is a temporary fix that lasts maybe an hour at best.  This is another one of those issues that is hard to communicate up to the correct department to get fixed.  Customer Service will have no real permanent fix for this regardless of what they tell you to do.  This is often an unfortunate problem with large corporations.  The people that can repair this are left out of the loop and it's left in the hands of customer service.  Let's keep calling and complaining maybe something will eventually get done.

Please share any updates

Samsung now trying to say xfinity issue.

Tried to sell me a new S23 from my S21. Told them not a phone issue 

Hi, @user_5cr927! Thanks for taking the time to reach out via our Xfinity Forums for help with sending and receiving emails on Samsung Galaxy devices. Apologies for any inconvenience this may have caused. Have you confirmed the correct settings are selected for a Comcast Email Account on Samsung Galaxy Devices? Here are the steps below:

1. From the Apps menu, tap the Email icon  and then the Settings icon 

2. Tap  > Email Settings, and then the @comcast.net account.

3. Scroll down and tap Server settings to verify Incoming settings and Outgoing settings.

4. For server and port settings, please reference instructions for configuring your email settings. Re-enter your password.

5. If changes are made, tap Done.

Xfinity asked me for my password an hour ago, I put it in, and all my emails are coming up now on my Galaxy, BUT this may change in another hour, because the same thing happened last night, and then my emails stopped coming in again!

I hope it works for you, but I think it's just temporary. :-)

Thanks. How do I get the safe mode? I used Xfinity hat support but they gave me a bogus answer I knew was wrong.

@GinJeannie​ 

Tried that - did not work for me unfortunately but thank you for the suggestion.

Hi, @user_rq6x2y I just wanted to follow up with you today to see how everything is working.

@user_ny26u9​ definitely a samsung issue. My best friend works at Comcast and it's not them.Restart your phone in safe mode, let sit, then restart

I doubt it is Samsung. My Gmail account is syncing fine, comcast account won't. 

@GinJeannie​ it's only a temporary fix though

Agree. My Gmail account is fine. Just Xfinity email is problem on S21 phone.

My outlook365 acct works . Just not comcast acct.

I have Tmobile.
