Can't share calendar...

[PA-WOODCHUCK]

Running office 365(classic mode) w/updates on our 2 home PC's I'm the account holder. I open calendar, select share, and no window opens up to select wife's name/email to share. Her PC is also shared on my MS account. What am I missing... can't be to hard(LOL)?

BTW I'm aging myself as I go way back to Win-3.1-yikes.

I enjoy your education

thanks
