If the Microsoft Exchange Server information store generates:

Event:9037
Source:MSExchangeIS Private
Type:Error
Category:None
Description: No database session was available to satisfy
 a request. The registry value
 SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersPrivate\Sessions
 may be set too low for the level of activity on this server.
you have exceeded the 60 Sessions (60 JET tables) which are opened during initialization. To increase the number of Sessions, use Regedt32 to navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersPrivate

Edit or Add Value name Sessions, a type REG_DWORD, and in the DWORD Editor, set the data value to Decimal 70. Click OK and restart MSExchangeIS. If event 9037 continues to occur, increase the data value till it ceases.

NOTE: Event 9037 is caused by slow response to the JET calls.

NOTE: Each JET table consumes additional RAM.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersPublic

Edit or Add Value name Sessions, a type REG_DWORD, and in the DWORD Editor, set the data value to Decimal 70. Click OK and restart the Public information store. If event 9038 continues to occur, increase the data value till it ceases.
