While MAPI is logging off a client after a call to the IMAPISession::Logoff method.
While MAPI is logging off a message store provider. In this case, IMSLogon::Logoff is called as part of MAPI processing the IUnknown::Release method of the support object that the message store provider creates while it is processing an IMsgStore::StoreLogoff or IUnknown::Release method call on a message store object.
