Does share calendar option works for shared calendar?
It does, but you need to have the entire shared mailbox added to Outlook, as additional account. Or do it via OWA's "Open another mailbox" functionality. In both cases, you need full access permissions on the shared mailbox.
Hi,
When I try using OWA I get this error "The sharing invitation couldn't be sent"
Regards.
Hm, well it works fine for me. Make sure you are opening the shared mailbox directly, not just selecting the shared calendar from your own mailbox. An easy way to do this is to open: https://outlook.office.com/owa/shared@domain.com/
Once you open the page, go to Calendar, select it, press Share, enter the email and press Share again.
I've tested even trrying the link you have provide it, but I got same error message even do the permissions are being applied, seems that the share notification is not being delived.
After giving me "send as" permissions the error message was not longer showing up and share permissions are being applied.
It seems that only OWA will work, I've tried with outlook by adding the shared mailbox as an additional account but the button appears as greyed out.
