"Email address invalid" when trying to send?

Dear Mr.Lucas2,

 

Good morning! Thank you for posting in the Microsoft Community. We will be happy to help you.

There could be several reasons why you are receiving the "Invalid email address" message when trying to send an email to someone outside of your contact list in Outlook for Mac.

Here are a few things you can try to troubleshoot this issue:

1. Have you checked the email address for typos or errors to make sure that the email address is entered correctly and that there are no extra spaces or characters?
2. Check your email account settings. Make sure that your email account is set up correctly in Outlook for Mac and that the outgoing mail server settings are correct.
3. Try sending the email from a different email client or webmail service. If you are able to send the email from another email client or webmail service, then the issue may be with Outlook for Mac.

If none of these solutions work, Let me know if you have any further questions or concerns. Please understand that our initial response may not always resolve the issue right away. However, with your help and more detailed information, we can work together to find a solution. Thank you for your help.

Is there a work-around to this?

Dear Mr.Lucas2;

Hope you are doing great.

To verify that you are using the correct email account settings in Outlook for Mac, you can follow these steps:

1. Open Outlook for Mac.
2. Click on the "Outlook" menu in the top left corner of the screen.
3. Select "Preferences/Settings" from the drop-down menu.
4. Click on the "Accounts" icon.
5. Select the email account that you are having issues with.
6. Verify that the incoming mail server and outgoing mail server settings are correct. You can check these settings with your organization admin.
7. If the settings are incorrect, update them and click "Save".

Once you have verified that the email account settings are correct, try sending an email again to see if the issue has been resolved. If you are still experiencing issues, please let me know and I will be happy to assist you further.

Hi, thanks for getting back so quickly, I realized that I am not using the Legacy Mac but the updated version. I appreciate your suggestion to "Check your email account settings. Make sure that your email account is set up correctly in Outlook for Mac and that the outgoing mail server settings are correct.",

I have looked through all of my various settings, how do I verify I am using the "correct" settings?
