'Modifying Exchange ACL for folders with python

while try to read the ACL Table of a folder, I ran into this problem:

In a C++ tool (MFCMAPI) this method is used to get the Property PR_ACL_TABLE in a usable data type:

// Open the table in an IExchangeModifyTable interface
 EC_H(lpMAPIProp->OpenProperty(
  ulPropTag,
  (LPGUID)&IID_IExchangeModifyTable,
  0,
  MAPI_DEFERRED_ERRORS,
  (LPUNKNOWN FAR *)&lpExchTbl));

I figured out to do this in python win32:

table = mystore.OpenProperty(mapitags.PR_ACL_TABLE, IID_IExchangeModifyTable, 0 , mapi.MAPI_DEFERRED_ERRORS)

But it seems that the MAPI Extension does not know the IID_IExchangeModifyTable type. I just got just this error:

AttributeError: 'module' object has no attribute 'IID_IExchangeModifyTable'

Does anybody know another way to get and modify the ACL data from exchange via the MAPI (and python)?

Thanks - Marquies

According to the docs, you need a PyIID object.

However, in almost all cases, functions that expect a CLSID/IID as a param will accept either a string object, or a native PyIID object.

That said, I've seen mapi.IID_IMessage used with the OpenProperty method.

IExchangeModifyTable is declared in edkmdb.h Are you using mapi33 in python? Is that interface even declared in mapi33? You can use RDOFolder.ACL in Redemption (I am its author): http://www.dimastr.com/redemption/rdo/RDOACL.htm

It looks like you are trying to access the ACL table on a message store object. As far as I know, ACL tables are specific to folder objects and don't exist on message stores. Try using your "mystore" object to open a particular folder within the store, and then call OpenProperty on the folder object to retrieve the ACL table. Make sure you open the folder object with the MAPI_NO_CACHE and MAPI_MODIFY flags specified as well.
