Convert mailbox to shared in Azure runbook

Question

Hello,

Trying to run automation in our environment for departing users through Runbook, when attempting to convert like I do through local powershell using:

`function setShared($email){

Set-Mailbox $email -Type Shared  

output "Setting mailbox to shared"  

}`

I get the error that -Type is not an acceptable parameter, what is the parameter I need to call through Set to allow the box to be converted to Shared?
