| Description | The Internet Mail Service administrator account is no longer valid. The Internet Mail Service will not start until you recreate the administrator account or configure the Internet Mail Service to use another administrator account. |
| Event Information | According to Microsoft: CAUSE: The error occurs when the Internet Mail Service is unable to obtain a pointer to the Internet Mail Service administrator mailbox during initialization of the service. This usually means that the Internet Mail Service administrator mailbox has not been set, is incorrect, or is inaccessible. RESOLUTION: Ensure that you set a correct, and accessible mailbox for the Internet Mail Service administrator mailbox. To locate the administrator mailbox, go to the Internet Mail tab of the Internet Mail Service properties. If no mailbox has been specified, you should specify one. If the mailbox is incorrect (if it does not exist, for example), change it to a different mailbox. If everything appears to be correct, change it to point to a different mailbox, click OK to accept the change, and then go back into the properties of the Internet Mail Service. Change it back to the original mailbox, and then click OK to accept that change. This should reset the mailbox internally. |
