If a Zoom meeting is being created automatically when a recipient is invited to a meeting, this can be disabled from the Outlook for the web calendar settings.
To turn this off:
1. sign into the Outlook web app: https://outlook.office.com/mail/
2. Click the settings gear icon at the top right.
3. Select "Calendar" on the left, then "Events and Invitations"
4. Uncheck the box next to "Add online meeting to all meetings", then click "Save" at the bottom.
It can take a couple hours for this to update, but once it does, it will no longer automatically create a Zoom meeting. You'll need to use the Zoom add-in button in Outlook to add meetings manually. This button may be hidden within the 3 dots at the top of the Outlook appointment for Mac users.
