Windows 10: Cannot receive or send from Windows 11 Microsoft Mail app. How do I fix it?

I cannot send or receive e-mail on this Windows 11 computer in the Mail app. If I use Spectrum my ISP "Webmail" on this computer, e-mail works fine. Microsoft support chat attempted to help me by remotely controlling my computer, but all their tests were negative. They could not send me an e-mail during any of their attempts. They finally recommended that I contact Microsoft's Outlook" team, but I do not know how to do that, and I thought that Outlook was a separate app from Mail.My e-mail address has been used for years and has worked on all four of my "Hackintosh" computers since 2014.

Windows 10 Mail App can receive mail but can't send it

I am trying to use the Windows 10 Mail App to send/receive email using my work email account. I am able to successfully receive email but everytime I tried to send a new email, it goes straight to the Outbox and never gets sent.

When I received email initially, I had to accept a certificate. I haven't been prompted to accept a certificate with sending but I suspect that is the hang up.

How can I get the Mail App to send emails?

 

Outlook Stuck on Send/Receive  

@bartjunited
I have one troubleshooting suggestion for you, but it's slightly advanced method to determine a problem, since you so far found no solution it might help you identify a problem.

Step 1:
Download process monitor: https://learn.microsoft.com/en-us/sy...nloads/procmon

Step 2:
Download my custom configuration for process monitor, find it in attachment

Step 3:
Extract archive to your Desktop or some other convenient location

Step 4:
Run process monitor as Administrator

Step 5:
Click on File -> Import Configuration menu and import the file from extracted archive called ProcmonConfiguration.pmc

Step 6:
Click on Filters -> Filter... menu and in a window that appears unckheck "TCP Receive" option and click OK

Step 7:
Run outlook to be ready to troubleshoot it

Step 8:
In process monitor click on red "trash bin" icon to clear all contents in process monitor

Step 9:
In office click on "send\receive" to start mail syncronization

Step 10:
In process monitor you'll see Cyan colored lines which indicate failed or closed connection or disconnection.
In the output you care only about outlook program (ignore the rest), specifically those ports which you configured for your mail in question
Make sure that for each such cyan line there is corresponding "TCP Receive" for outlook program

If there is no matching "TCP receive" this mean you identified a problem which is that outlook fails to communicate with google for given mail configuration.

If that's the case your next step is to reconfigure mail configuration and try again troubleshoot it.
You'll know your modification to mail configuration works when you see coresponding TCP receive operation.

 

Mail not sending!

Your last reference was to Mailbird- it seems you've reverted to Mail.

The choice of pop3 or imap for receiving mail is up to you.. smtp is a different thing.

Suggest you try sending mail with Mailbird
