We have ran into an issue where the sophos_detoured.dll included with Sophos 9.5.x is causing our machines with outlook 2007 Sp2 to hang (XP SP3).
After a few days of troubleshooting with microsoft, they pointed us in the direction of the sophos_detoured.dll.
Renaming the sophos_detoured.dll "fixes" the issue.
Here is what we have:
Any machine with the configuration mentioned above that has never turned on reading pane is fine.
If reading pane is enabled, it crashes until all add ins are disabled.
If reading pane is enabled and then disabled, it crashes until all add ins are disabled..
We can consistently recreate the issue on all of our machines.
Sophos cannot recreate the issue but has acknowledged a very small population of clients exhibiting the same error.
Anyone out there seen this and have a fix that does not involve renaming the dll and thus rendering BOPs useless?
This is the only KB with any mention of an issue on this file http://www.sophos.com/support/knowledgebase/article/112099.html
Sophos recommendation is to rename the path of this file in the registry so that the dll doesnt load until they have a permanent fix.
Adding outlook.exe to the Application Authorization on Buffer Overflow has no effect on the issue and neither does turning off BOPs through policy.
