Identify store/folder uniquely

Hi all,

I need to ensure each time my application runs, it opens one Contacts folder
and performs operations on it.

MAPI.Folder myFolder = (MAPI.Folder)session.GetFolder(folderID,
storeID);

However, every time I open a session and iterate through stores via
session.InfoStores, the same store has a different ID (store.ID). What's
interesting is the fact that the IDs seem to look alike, e.g.

"FF00000038A1BB1005E5101AA1BB08002B2A56C200018E76EA38F2152D40822DFCB17DA4875
6"
"FF00000038A1BB1005E5101AA1BB08002B2A56C200010AC217A5E4267241979283ACD0CD06F
A"
"FF00000038A1BB1005E5101AA1BB08002B2A56C20001CFCDAD7924D7B347A9CCDF7ACB920CB
F"

These are the IDs of the same store when I run my application 3 times in a
row.

What's the best way to accomplish my objective? How can I be sure to open
the right folder each time?

Thanks,

-Oleg.

Oleg,
mostly likely you get short-term entry ids (ID) which can
only be used in the current sesstion. Open the object using its short term
entry id first and read ID from the object itself

From MSDN:

=======================================
When a client accesses an entry identifier through a column in a table, most
likely this entry identifier is short-term rather than long-term. Short-term
entry identifiers can be used to open their corresponding objects only in
the current MAPI session.

Entry identifiers come in two types: short-term and long-term. Short-term
entry identifiers are faster to construct, but their uniqueness is
guaranteed only over the life of the current session on the current
workstation. Long-term entry identifiers have a more prolonged lifespan.
Short-term entry identifiers are used primarily for rows in tables and
entries in dialog boxes whereas long-term entry identifiers are used for
many objects such as messages, folders, and distribution lists.

=======================================

Because Session.InfoStores wraps IMAPITable nterface, all EntryID (ID) in
this table are short-term (valid inside This MAPI session).

So, is there a way to get a long term entry ID?
If not, in what format do I store the path to the folder so that I could
open the folder each time my program runs?
Do I have to iterate through all stores/folders? This just seems
inefficient.
Thanks.

-Oleg.

StoreID should always be the same. EntryID is what is short-term or
long-term and that only applies with Exchange. With a PST file the EntryID
is always the long-term one.

The property tags for short-term and long-term IDs' are:

PR_ENTRYID = 0xFFF0102
PR_LONGTERM_ENTRYID_FROM_TABLE = 0x66700102

Found it, I just needed to read the CdoPR_STORE_ENTRYID (&H0FFB0102) field.
