I use Aspose to iterate through emails in OST file, everything works as expected. But I want to understand about MesageInfo.EntryId
Using Aspose the value of email I am searching is shown as
EntryIdString ==> AAAAAIa2dblwPEFPktTf5VQdPIBE5SIA
EntryId ==> 00-00-00-00-86-B6-75-B9-70-3C-41-4F-92-D4-DF-E5-54-1D-3C-80-44-E5-22-00
But if I use Outlook Iterop library the EntryId looks like below 00000000ED906AE5C139804E945AA0A373CC962507004AF2CAE6A0174440BCDDA7DF32DC94F600000000010C00004AF2CAE6A0174440BCDDA7DF32DC94F600003611AC640000
I also try to use Outlook Spy tool to look in to the mail properties and found that EntryId matches what interop is showing.

I tried to create new message file and I see newly created mail EntryId matches Aspose and Interop. So something to do with my existing emails and I won’t be able to share my entire OST file.
Can I just understand the EntryId from MessageInfo object is always from PR_ENTRYID MAPI property (Tag num: 0x0FFF0102)?
How EntryIdString is calculated?
