Meeting invitation being initiated from wrong email in via Desktop to Outlook

Using Desktop app to create a meeting which then it pops into Outlook. Outlook the email that I have Zoom registered with and is also the default one in Outlook is greyed out and wants to use secondary email. 

My default email that Zoom is registered with is also the default email that is the default on inside Outlook. 

I had a 3rd email acct in Outlook and before deleting that it was also an option, so both of the accts that were not primary in Outlook were fine to send meeting invitations but not the one that is the primary for Zoom and Outlook. 

If I generate a Meeting from within Outlook via the add-in - it picks the correct email. 

Generating meeting from the online site also picks the correct email for invitations.

I tried reinstalling Zoom. No dice.
