Service accounts set up with mailbox hosted on O365.

Hey guys,

Trying to find the best way to modify our service account function to create mailboxes on O365 by default, as opposed to our on premises Exchange server.

This is the stuff I am working with. I have tried enable-remotemailbox but I can’t set the SendReceiveQuotas that way. So what would be the best way to get this done in your guys’ opinion?

Or at what point should I check to make sure I am connected to Office 365 to get the settings correct?

Thanks all!
