In the Calendar app on my MBA (M1, Golden Gate 27.0), I have my Google account signed in so that my Google Calendar is reflected in the Calendar app. Whenever I create a new event and go to "Add Invitees" and start typing in my girlfriend's name, I get four email addresses that populate - two of which are good and the other two which are old and no longer in use. I want to get rid of the two older and defunct email addresses from auto-populating when I type her name, but cannot figure out where these two old email addresses of hers are getting pulled from.
I've spoken with a couple of different senior support specialists from Apple and have done the following troubleshooting steps with no luck: deleted contacts from Google contacts, deleted emails from old email addresses, deleted calendar events mentioning or sent from old email addresses, cleared recent locations and attendees, checked past events, updated contacts app, toggled calendar off and on, cleared out other contacts, disabled birthdays in calendar, deleted contacts from trash, created from iCloud.com and no contacts found.
Can anyone offer any insight on how to possibly resolve this issue? I'm not quite sure what to do at this point.
