EntryID

[Arne Baldauf]

Hello,

I am currently writing my own Outlook sync tool (using C#), as I could not
find any tool which is available for free and which meets my requirements
(synchronizing any folders and items on my notebook and pc).

There is still much work to be done, but at least I have succeeded in
reading the full contents of an outlook store and mapping some of the basic
information to a xml structure (for comparison of changes since the last
sync). So I have some questions about the information to gather (which are
not c# specific (which is the reason why i post this to the vba group)):

- Is the "EntryID" of every item througout the whole folder hierarchy a
unique one?

- Is the "EntryID" a fixed value, especially when duplicating an entry and
moving it to another store (read: .pst file)?

- Does the "LastModificationTime" get changed when doing basic operations
which do not affect the primary contents of an item (such as "marking as
unread" or the like)?

Thanks in advance,

Arne

1. In a folder all EntryIDs are unique.

2. There´re different ways to change an EntryID. Moving the item into
another *.pst is one of them.

3. Flagging the item as read doesn´t change the LastModificationTime. You
can use a tool like OutlookSpy (www.dimastr.com) for exploring these
informations.

My two cents: If your app is really finished then you´ll know that spending
e.g. $60 for a good sync tool is very much cheaper than developing it
yourself

Thanks for these informations.

1.) As I am a student at the moment I'd prefer to spend my limited amount of
money on hardware instead of software that I could write for myself instead.

2.) I like to take the challange of it

3.) None of the tools which I found are to my liking, and the only one that
does (demo version) crashes at the end of the sync process..

Kind regards, Arne

A good answer.
