Hi @Laura Gaunt ,
Welcome to our forum!
Client A schedules appointments directly into my Outlook calendar using my Client A email address.
Does Client A give shared permission to you to access his calendar and you add his calendar in your calendar?
I would like to set up automation in my Client A Outlook Calendar so that every time a meeting is made within in, it triggers an automatic invite into a different calendar for Client B using my client B email address.
The most convenient way is to create a rule for Client A email address to forward all meeting invitations to Client B email address via File>Manage Rules & Alerts>New Rule. More information: Manage email messages by using rules.
Hope to help you!
