Today I was informed by the 1st level support that they receive several calls from users who have problems to open their e-mails or attachments in Outlook. The following screenshot shows the error message shown in Outlook:
Translation: Impossible to open the element. Impossible to execute the operation, not enough memory.
I've tested this on my Outlook and the symptom was that I saw the list
of e-mails but when I tried to open an e-mail message, the new window
for the mail opened but the content of the mail was empty. However no error message was shown in my Outlook (2007).
Note: This only happened once I disabled the local cache in Outlook. Before that, with the local cache activated, mails were shown fine.
As this happened to many users at the same time, the source of the problem is easily located on the Exchange 2003 server.
Indeed, after a quick research in the Application Event Log, the following error was found:
Event ID: 9582
Description: The virtual memory necessary to run your Exchange server is fragmented in such a way that normal operation may begin to fail. It is highly recommended that you restart all Exchange services to correct this issue.
According to KB 325044 this problem occors when the available space of the virtual memory of the Store.exe process (Information Store) declines. The thresholds are the following:
Such a second Event Log entry was found just 4 minutes after the first error:
Category: Content Engine
Event ID: 12800
Description: Message processing failed because there is not enough available memory (8007000E-820003A2).
To temporarily resolve the problem, the MSExchangeIS service can be restarted. But this is only a temporary solution, as the virtual memory fragmentation will most likely return.
The way to handle this error more properly, the following steps should be made (maybe even more, do whatever is in your power to increase stability!):
