EWS Returns a diffrent EntryID on an item in a public folder than Outlook RRS feed

  • Question

  • Hello,

    I have discovered a problem with the managed EWS API when retreiving a mail item from a public folder on Exchange 2013 AND Office 365.

    The EWS will return the ewsid, and converted to an entryID, but it does not match the same entryid as Outlook sees. I have traced it to the parent folder of the item. This folder returns a diffrent entryid for the same mail item.

    Could this somehow be related to the new location of the public folders ?

    When I do the same on items in a private mailbox the EWS - entryID and Outlook - entryID match 100%

    I have listed the EntryID of the same item as identifyed through EWS and Outlook SPY

    Item EntryID: 00000000828CE19FAFD17D4CBC3105AC5AE0EEFD0700660CE6110D284D488E75E0EC9E2812450000000000130000660CE6110D284D488E75E0EC9E2812450000000000190000
    Folder EntryID:

    Item EntryID:

    Folder EntryID

    Any input is welcome
