Windows 10: I cannot send or receive emails in my Microsoft mail program

I have not been able to send or receive emails in my Microsoft Mail program for several days. However, both my cell phone and Gmail account have not been affected. I was able to speak with a Microsoft rep by phone on Sept. 11 and he said the problem was corrected. But the same problem began again 2 days later. Microsoft is no longer taking phone calls so I tried to resolve the issue by changing my password which they requested in one of their auto message notations. It did not help.

Attention required message under email account, cannot send and receive mail from a linked account

Hi Sharon,

You might not been able to send or receive an email due to a misconfigured account settings. For us to isolate the issue, we would like to ask the following questions below:

• Which application or program are you using to access your email?
• Have you encountered any error message?
• What troubleshooting steps have you done so far?

If you are using the Windows 10 Mail app, we suggest that you remove your email account and re-add it.

We will wait for your response.

 

Office 2013 Mail Merge sending no emails

I used to have no problems sending a Mail merge on Windows 7, however, trying to do one today on Windows 10, and it's simply not working.

I've done everything the same, using an excel document as the data source, and that works fine. When I select Finish & Merge -> Send Email Documents and then OK, Word makes it appear it worked (all the dynamic values change to those of the contacts as it cycles through sending each email), but that's it. Not one email is sent; nothing in my sent items and nothing shows that any of those contacts have been email on our exchange or email archive software.

I've seen that people suggest that Outlook is my default app (it is). Double checked the registry key as well Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\(Default) has the value Microsoft Outlook.

I've literally done nothing different from when doing this on Windows 7; seems that the searches seem to suggest that it's a common problem as well, but everyone seems to say they had a problem and disappears from their support request (and most answer tell you to check the above registry key).

 

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?
