Evaluating performance and limitation for bulk item update using GetItems and UploadItems EWS requests (Exchange 2010) RRS feed

  • Question

  • Hi, we are investigating the limitations and performance advantages for performing bulk update on exchange items (would be Contacts and Calendar Items, possibly email too) using our Java middle tier applicaitons commucating with Exchange 2010. Regarding this I have 3 questions:

    1. Limitation for number of items that is allowed in one UpdateItem or CreateItem request? Would EWS 2010 optimize the performance for such bulk update in this case? Any estimate for optimal number of items without considerable deterioration of performance?

    2. Is there any advantage (performance-wise) over UpdateItem to use UploadItems instead (assuming the items are not emails and there is no attachements)? What is the limitation for number of items there?

    Thanks,

    Vladimir
