When using Enterprise Vault (EV), the following error occurs: Event ID: 3230 - Timed out whilst waiting for the MAPI profile mutex.

Error Message

Event ID 3230 : "Timed out whilst waiting for the MAPI profile mutex."



When using EV, this error message may be logged by any of the agent services ie. Archive, Retrieval, Public Folder Services/Tasks.
The error effectively means that a Messaging Application Programming Interface (MAPI) profile could not be created, or the connection to the Exchange server/s was lost.
However the error can occur for other reasons, including the following:

  • Connection to the Global Catalog(GC) server/s could not be made or is lost.
  • Connection to the Domain Controllers(DC) could not be made or is lost.
  • Connection to the SQL server hosting the Enterprise Vault (EV) databases could not be made or is lost.
  • Issues with Outlook and/or Collaboration Data Objects on the EV server.
  • Mis-configured EV server.

A MAPI mutex error is a critical error, so when this occurs, the EV services and/or tasks are shutdown.


MAPI mutex errors can be minimised by performing the following:
  • Restart of the Agent services/tasks on a daily basis. - This will clear/reset the MAPI resources in use or resources that could not be cleared successfully.
  • On very active EV servers, update the ProfileExpire registry key value on the Enterprise Vault server to a lower number.
Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.
If the Enterprise Vault server runs a 32 bits OS:
HKLM\Software\KVS\Enterprise Vault\Agents\ProfileExpire

If the Enterprise Vault server runs a 64 bits OS:
HKLM\Software\Wow6432Node\KVS\Enterprise Vault\Agents\ProfileExpire
The default for this setting is 3 . This represents the number of days before systematically created Outlook Profiles are expired.  Changing this value to 1 (day) will expire the systematically created Outlook Profiles faster, improving overall Outlook performance.
Note:  Setting this key to 0 will clear all Outlook profiles created by the EV services and tasks upon EV service restart; however, this key should be changed to a value greater than 0 for normal operation.
