I currently have Microsoft 365 Outlook and want to change to Gmail. I tried to add the Google preset MX records to my Squarespace DNS section, but it failed. (The Google MX settings are in there but greyed out.) Is this because I did not delete the existing DNS/MX records? (There are 21 of them.)
If I delete the existing DNS records, will that disable my current 365 email, and then I won’t get email until Google kicks in a few days from now?
