Note The description of this event may vary depending on the object type.
Note Microsoft Exchange Server 2003 Service Pack 1 (SP1) increased the default value of several server objects. The increased values are shown in the "SP1 and later service packs" column in the following table.
|Entry||Default Value||SP1 and later service packs|
Additionally, investigate the user behavior that is associated with the indicated logon. This will help you better understand why the default number of objects is insufficient. In rare circumstances, the number of resources is insufficient and may be adjusted. However, use caution before you adjust the maximum number of objects that are allowed. When you increase the maximum number of objects of a particular type, you also increase the amount of memory that may be consumed by client requests. Incorrectly configuring this value could lead to out-of-memory warnings or virtual memory fragmentation warnings.
You can add a registry key that adjusts the maximum number of resources that a MAPI client can use at the same time. This adjustment overrides the default limit of each server object that is mentioned in the "Cause" section.
Note You should only adjust the value for the object type that is referred to in the event log error that is mentioned in the "Symptoms" section. You should adjust these values with caution, and only increase the value in small increments. For example, only adjust the value by 100.
