Unable to use invitees on Calendar.
The Add Invitees option is not displayed in Calendar on my MacBook Air.
The Calendar is syncing with my iPhone and I can add Invitees on the iPhone.
In the iCloud section of System Preferences I do not have Mail checked. When I do check this box I am asked to create an email account but this fails. Do I have an iCloud eMail account I don't know about?
Clearly my MacBook isn't set up correctly so any help would be appreciated.
MacBook Air (2018 or later)
