EWS API ExchnageWebServices Update() method on Contacts

Question

Will updating just a few Contact properties like say "JobTitle" for a single Contact object using EWS Managed API will overwrite the whole Contact and just set a JobTitle properti or will it just update that Property and preserve the other values?

I wish the documentation for this API was better.

Thank you in advance.

Answer 1

Changes are made at the property level in EWS so it will just update the property you change (when you say "other values" what are you expecting to be overwritten?). But the best thing to do is actually write some code and test it yourself as there are some exceptions are DisplayNames etc.
