SYMPTOMS

If you use the IDataSource.Save method after you install Exchange 2000 Server Service Pack 2 (SP2), you may receive one of the following error messages:
80040E94: Caller requested write access to a read-only object
-or-
80040E09: Permission Denied

CAUSE

This behavior occurs because of a change in the implementation of the IDataSource.Open method in the CDO for Exchange 2000 (CDOEX) Library. By default, the Open method opens access to an object as adModeReadWrite in versions of Exchange Server earlier than Exchange 2000 Server SP2. However, in Exchange 2000 Server SP2, the Open method opens access to an object as adModeRead by default.

RESOLUTION

Call IDataSource.Open with the adModeReadWrite parameter before you call the IDataSource.Save method, as follows: 
 oObject.DataSource.Open strSourceURL, , adModeReadWrite

STATUS

This behavior is by design.
