MX Record invalid format

I have a domain through Google and work email through Microsoft. When I try to add the MX Record from Microsoft to Google, I get the error message "Invalid Format". I don't know what other way to get around this in order to start receiving emails. Can someone please help me with this issue?

    I think this issue is largely created by the common mistake in which the Priority value on the Microsoft Domain page is ignored when entering a value into the Data field on the Google Domain page.

     

    When you enter the info into the Data field of the Google Domain page for the MX record, it's actually a combination of two separate fields from the Microsoft Domain setup page called Priority and Points to address or value.

     

    So, for example, if the MX record in Microsoft Domain setup page state the Priority value is "0" and the Points to address or value field shows the value of "xxxx.com.mail.outlook.com." then when completing the "data" field on the Google Domain page for the MX record, it should read "0 xxx.com.mail.outlook.com."

      TKO_888 I did this and it appears to work somewhat better than before.  However, I'm now receiving 'invalid entry'.  Any other recommendations?

        SLE2022 Not sure, if you want to screenshot the fields on your domain page and then what you entered into Microsoft field that is prompting the error, maybe we can see something to help?

      Excellent and helpful content. For some reason neither Google nor Microsoft bothered to address this issue in their UI. Content and guidance of this post should be part of the context help on the page of both Google domain DNS management page and Microsoft page for connecting with existing domain, which can be shown on hovering mouse over the help icon next to that respective row. Most of the times inertia becomes directly proportional to the size of organization. Thanks again for your guidance.

    I found a fix that worked for me...I put the number "1" before the domain name and it was accepted.
