Windows 10: Windows 10 Mail BCC is not sending emails to gmail accounts

I regularly send emails using BCC to approx. 20 email accounts. I have never had a problem with this in Outlook or anywhere else. On Windows 10 Mail I have realised that the BCC fails to deliver the email at all to any gmail recipient - no error message, they just seem to be stripped.BTW I have seen advice to check the BCC list after sending via the Properties of the sent mail item, unfortunately no such button seems to exist this latest version of Windows Mail seems to have been dumbed down to the point of unusability - is this an Outlook marketing effort on Microsoft's part?Also be clear t

not sending or receiving gmail in mail app on Windows 10?

since Wednesday September 9 I have not been able to send or receive any gmail emails on the windows 10 mail app on my pc. My Hotmail account is working okay, both were added . Also , I don't know how to access my contact list on this app to add a bcc or
just look up an address

Hi Robbyn,

To isolate the issue, please provide the following information:

• What error message do you see when you try to send a message using the BCC field?
• Does it only happen when the BCC field is populated with the recipients' email addresses? Or, does it happen even when both the To and BCC fields are populated?
• Are you sending from an imported account on Outlook.com? An imported account is a third party email address that you added on Outlook.com (e.g. Gmail, Yahoo, etc.).
• Were there any changes on your computer or Outlook.com account settings prior to the issue?
• What troubleshooting steps have you tried so far?

Regards.

 

Windows 10 Mail BCC not working

Sending from Windows 10 Mail using Blind Carbon Copy and the recipient receives mail with all the recipients email addy's. I don't use it much myself, but a friend does and sure enough, I tried bcc and the emails are visible along side the bcc.
