This bug was one the toughest for me to identify and implement a workaround as

• It happens only one time in each session
• Quick glance at the form during create does not provide any clues regarding the bug

The bug is this: When a new appointment is saved, the organizer field is not set even though it shows the field being populated during form load and save.

Here is how the appointment form looks when you create a new appointment:

The organizer field appears to be populated, but it is not. This is the dataxml:

<appointment>
	<instancetypecode>0</instancetypecode>
	<prioritycode>1</prioritycode>
	<scheduledstart>2017-07-07T11:30:00</scheduledstart>
	<ownerid type="8" name="Natraj Yegnaraman">{40327227-A570-E611-80FA-005056A6A11C}</ownerid>
	<scheduleddurationminutes>30</scheduleddurationminutes>
	<isalldayevent>0</isalldayevent>
	<scheduledend>2017-07-07T12:00:00</scheduledend>
	<statuscode>5</statuscode>
	<transactioncurrencyid name="Australian Dollar" type="9105">{F0B901CE-7692-E211-82F1-0050569B4EC3}</transactioncurrencyid>
	<isbilled name="">false</isbilled>
	<ismapiprivate name="">false</ismapiprivate>
	<attachmenterrors name="">0</attachmenterrors>
	<isworkflowcreated name="">false</isworkflowcreated>
</appointment>

Compare this with the dataxml when the organizer field is really populated:

<appointment>
	<instancetypecode>0</instancetypecode>
	<organizer>
		<activityparty>
			<partyid type="8" name="Natraj Yegnaraman">{40327227-A570-E611-80FA-005056A6A11C}</partyid>
		</activityparty>
	</organizer>
	<prioritycode>1</prioritycode>
	<scheduledstart>2017-07-07T11:30:00</scheduledstart>
	<ownerid type="8" name="Natraj Yegnaraman">{40327227-A570-E611-80FA-005056A6A11C}</ownerid>
	<scheduleddurationminutes>30</scheduleddurationminutes>
	<isalldayevent>0</isalldayevent>
	<scheduledend>2017-07-07T12:00:00</scheduledend>
	<statuscode>5</statuscode>
	<transactioncurrencyid name="Australian Dollar" type="9105">{F0B901CE-7692-E211-82F1-0050569B4EC3}</transactioncurrencyid>
	<isbilled name="">false</isbilled>
	<ismapiprivate name="">false</ismapiprivate>
	<attachmenterrors name="">0</attachmenterrors>
	<isworkflowcreated name="">false</isworkflowcreated>
</appointment>

Also, notice that the Organizer field does not have a person icon next to the name, like the Owner field.

This is fix I implemented to workaround the issue:

	var organizer = Xrm.Page.getAttribute('organizer').getValue();
	if(Xrm.Page.ui.getFormType() === 1 && !organizer){
		Xrm.Page.getAttribute('organizer').setValue(Xrm.Page.getAttribute('ownerid').getValue());
	}

The script basically runs on form save provided it is a new record, and copies the Owner lookup value to Organizer lookup, if the Organizer lookup does not contain any value.

The reason the Organizer field is important is because, without this being set, that appointment won’t show up in the appointment creator’s Outlook  (even though they created it and they are also the owner).

This issue is happening in 8.1.0 and has been possibly fixed in 8.2.0.
