IMAP/SMTP authentication blocked – need mailbox reset

My Comcast email works when I log in through webmail, but all third-party email apps (Apple Mail on iPhone and Gmail) fail to connect and return “username or password is incorrect.”

I have already:

  • Reset my password multiple times
  • Confirmed I am using the full email address as the username
  • Verified correct IMAP (imap.comcast.net, port 993, SSL) and SMTP (smtp.comcast.net, port 587, SSL) settings
  • Toggled third-party email access off and back on
  • Deleted and re-added the account on my device

Despite this, authentication continues to fail in all apps.

This appears to be an IMAP/SMTP authentication block or security restriction on my mailbox. Please remove any blocks and re-enable full third-party email access.

I lost 10 hours yesterday trying to troubleshoot and went through ALL the same motions that

user_8n7qt2 describes

Had to ring Xfinity 2x before my husband's and our accounts (we have 4 comcast.net emails) to escalate to advanced technical support, only to hear from the Technician that she's been hearing a lot of complaints from callers yesterday.  For heaven's sake, Xfinity - you need to OVERCOMMUNICATE to your (inititally) loyal customers what you are doing and how you're going to handle your customers while you work this Yahoo server transition.  Between this episode and still not recovering our emails plus Xfinity's battle with Scripps -- it feels like we're enough pain that it makes sense to convert to solutions away from Xfinity.  Really poor  project planning Xfinity--you were supposed to be better than this.  Argh!
