Converting a User mailbox to a Shared mailbox in Exchange Online is easy enough, however this does not replicate to Exchange on prem, this can be done by editing
the Attribute value for "msExchRecipient TypeDetail" in Active Directory.  RemoteSharedMailbox attribute value is 34359738368, UserMailbox is 1, SharedMailbox is 4 and RemoteUserMailbox is 2147483648.
