If you have the iManage FileSite add-in for Microsoft Outlook installed, Microsoft Outlook 2010 may hang or stop responding.


This problem is caused by a possible incompatibility between the iManage add-in and Microsoft Outlook 2010.

A hang dump analysis has shown the cause to be the imanage.dll.


To resolve this problem, please use the following steps to disable the iManage FileSite add-in. If the hanging problem is eliminated, we recommend you contact Autonomy, the vendor of the iManage FileSite add-in to inquire about an updated version of the add-in. 

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
