How to change Sender info when writing to a PST RRS feed

  • Question

  • I am building a connector that uses EWS API for Exchange 2010 SP1 and newer using C# to collect contents of a mailbox. Having difficulty with meeting invitations (calendar items) that contain attachments. When I collect those calendar items and their associated attachments, the Sender information lists as UNKNOWN. 


    Does anyone know how to change the meeting organizer for calendar items in a PST?

    As EWS is an Exchange Mailbox API you can't use EWS to access messages within a PST file. So you questions doesn't really make sense given the description you posted ? Are you using EWS or MAPI ? you might want to try posting a sample of the code your using.

    You can't modify the Sender/organizer of an Appointment once its been created in Mailbox no matter the API you use. If you using FindItems in EWS to get information on Items then you need to make sure you use GetItem (or Load,LoadPropertiesfromItems) to get the Recipients and Sender information for a Message.
