Hi,
So I've finally found a simple way to make it easier for users (from the web) to set the "regardingobjectid" automatically in appointments using javascript. In this case, I created a number of lookup fields which get shown depending on certain criteria. In the online and mobile version, onchange of one the lookupfields, the value gets assigned to the regardingobjectid and all works perfectly.
However .... in outlook, all of the javascript is working except for setting the chosen lookupvalue from one of the lookupfields to the regardingobjectid lookup field. It simply doesn't do anything.
Is there a workaround for this so the regardingobjectid's functionality is also working in the outlook client through javascript?
