Late last year we instituted an approval process for travel booking, wherein after the traveler books a trip it needs to be approved by the person noted in their profiles as 'travel manager' before being finalized by our TMC. I have been hearing a lot in recent months that these approvers, and the occasional assistant who does approvals for an executive, have the approved travel added to their outlook calendars (we are using O365) and it's making a mess of things. Is there a way to shut this off that allows the approver to still get their own items added? If not, is there at least a way to shut it off, in general?
