Outlook calendar permissions and forwarding invites

Hi Charlotte

The person who owns the account you wish to forward messages from can grant you additional access by going to Accounts Settings - Delegate Access

From here if they change the permissions, for the calendar, to Editor this will give you the ability to not only Read, but to Write (sending to others) any invites.

You should be able to view the persons calendar in your own outlook, check the Calendar boxes (normally located bottom left of the screen).

I hope this helps.

Kind regards#
