设置EWS约会/任务RTF正文

Question

How can I set a ewsAppointment/ewsTask rtf body? Looks possible through an extended property, but I can't get this to work.

I was trying with getting the extended property like this -

ExtendedPropertyDefinition epd = new ExtendedPropertyDefinition(
DefaultExtendedPropertySet.PublicStrings,"PR_RTF_COMPRESSED",MapiPropertyType.Binary);

and setting it to a byte array of my rtf text - but that's not working.

Also - I'm trying to figure out if I should stick with html/rtf. Looking at EWS manged API - Appointment with Html Body and Outlook 2013 and links on that post, it sounds like it might be safer to always set RTF. Is this correct?

Thanks!

Answer 1

Your property definition is incorrect it should be

ExtendedPropertyDefinition epd = new ExtendedPropertyDefinition(0x1009, MapiPropertyType.Binary);

as per https://msdn.microsoft.com/en-us/library/office/cc815911.aspx because this is a tagged property.

it sounds like it might be safer to always set RTF. Is this correct?

With Contacts and Appointment generally yes but you need to make sure you get the CompressedRTF format correct. You may also need to modify some of the other properties listed in https://msdn.microsoft.com/en-us/library/hh369831(v=exchg.80).aspx
