Outgoing SMTP SERVER NOT WORKING

I have been using outlook to check my comcast emails for at least 10 years now. Never an issue. All of a sudden last night I could not send anything from outlook.   No password changes.  No changes period.  
I get a message that says there is an error connecting to the smtp server. 
I can't send emails through Outlook on my laptop nor through the mail application on my iPhone or iPad. I get the same message on all devices. I've called Comcast and wasted 4 hours during the day. Missed work trying to get this fixed. At the end of the call they said they can't help me anymore and that I should call Outlook. When I asked about the same error on my iPhone and iPad they didn't have an answer. I called Microsoft and they did several test at over an hour and told me try diff port and encryption combinations with no resolution.  After all this wasted time I'm still getting the SMTP server connection error message.   I'm using Outlook version 2016, any help is appreciated.

Re: Outgoing SMTP SERVER NOT WORKING

The error message from Microsoft when testing outgoing email server on my laptop says:
Outlook cannot connect to your outgoing SMTP email server. If you continue to receive this message contact your ISP.

Message on iPhone & iPad when checking Comcast email Through mail App (not Comcast Mail app) says:
The connection to the outgoing
server smtp.comcast.net failed.

I log in to my Comcast email via the xfinity website just fine so it’s not a password issue.
Any help is appreciated

Re: Outgoing SMTP SERVER NOT WORKING

After more time with comcast support and Microsoft support yesterday; no solution

 

The server set up information the provider (Comast) gave my husband during several comcast supports calls on Tuesday; and the same server set up information given to me on continuring comcast support calls on Tuesday as well as further comcast support calls yesterday was invalid. 

Comcast kept trying several server set up combinations and none worked.  

 

 Miscrosoft dialed into my computer and accessed the set up this morning and entered one of the combinations that was already tried on Wednesday and it was fixed it in 5 minutes.

I'm having the same issue with the Mac mail app and Comcast SMTP outgoing mail.  It doesn't recognize my name and/or password.  Do you have any idea what setting change worked for you?
