Store.exe and Exoledb.dll file version mismatch
Topic Last Modified: 2009-04-07
The Microsoft Exchange Analyzer Tool examines the file versions of the following Microsoft Exchange Server 2003 files:
If these files have different file versions, Exchange Analyzer generates the following error message:
'Store.exe' and 'Exoledb.dll' file versions mismatch on server <ServerName>. This may cause 'Store.exe' process to crash when users attempt to log on to Exchange Server 2003 Outlook Web Access (OWA).
When users log on to Exchange 2003 from Outlook Web Access, the Store.exe process may stop responding (crash). This issue may occur if the following conditions are true for each scenario:
The Store.exe file is version 6.5.7653.8 or a later version.
The Exoledb.dll file does not have the same version as the Store.exe file.
The Store.exe file version is earlier than version 6.5.7653.8.
The Exoledb.dll file version is 6.5.7653.8 or a later version.
This kind of situation may occur when one file is successfully updated, but the other file is not. For example, an update may include new versions of the Store.exe and Exoledb.dll files. However, when you install the update, the Exoledb.dll file is not updated successfully.
To address this issue, follow the steps in Microsoft Knowledge Base article 959254, "When you try to access Outlook Web Access, the Store.exe process stops responding, and event IDs 7031 and 1000 are logged in Exchange Server 2003" (http://go.microsoft.com/fwlink/?linkid=3052&kbid=959254).
