The information store can cause undue memory pressure to a system that has a large number of users. This causes performance issues for Messaging Application Program Interface (MAPI) and non-MAPI users. In extreme cases, the information store may not respond to remote procedure call (RPC) requests.
When a message has attachments, a subobject is created on the message object for each attachment. The system allocates memory for each attachment subobject. When you have messages that have many attachments, the information store may erroneously keep memory allocated for these subobjects even when the objects are no longer needed and can be destroyed. System memory is not freed up if these subobjects are not destroyed.
