Symptoms


Customer may login via Microsoft Outlook to Exchange mailbox with disabled MAPI access.
 

Cause


Mailbox properties stored in the Active Directory (such as ProtocolSettings) are cached in the MBICache (default TTL = 2hrs) and in DSAccess (default TTL = 15 min). These caches may delay the time it takes for a change in the ProtocolSettings to become effective.
 

Resolution


To change cache update period for Exchange Information Store perform the following steps:

  1. Run Registry Editor on the Exchange Back-end server.
  2. Locate the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\MSExchangeIS\ParametersSystem
  3. On the Edit menu, click Add Value.
  4. Enter Mailbox Cache Age Limit for the Value name.
  5. Type REG_DWORD for the Data type.
  6. Type 5 for the Data of type DECIMAL, and then click OK (Exchange server rereads the cache every 5 minutes).
  7. Restart the Exchange Information Store service.
