@K8ander Hi Kate, a Team comes with a shared calendar by default which is where invites to channel meetings come from, and this can be shown in Outlook depending on your M365 group settings (although I think you might need some PowerShell code depending on a few things - I will defer to someone more technical for this advice)
I am (always) curious about what is driving the need for shared calendars though? e.g. what is the use case?
