Possible Outlook hang if the iManage FileSite add-in is enabled

Applies to: Microsoft Outlook 2010


When using Microsoft Outlook 2010 with the iManage FileSite add-in for Microsoft Outlook installed, Microsoft Support teams have seen issues where Microsoft Outlook 2010 may hang or stop responding.

Note The use of the iManage FileSite add-in for Microsoft Outlook does not necessarily mean you will see this symptom. And, there are definitely other causes for Outlook to hang or stop responding. This article is merely intended to help you identify possible causes of this symptom when using Outlook.


This problem may be caused by an incompatibility between the iManage add-in and Microsoft Outlook 2010 in some circumstances.

A hang dump analysis performed by Microsoft support has shown the cause to be the imanage.dll.


If you are experiencing a hang in Outlook 2010 and you have the FileSite add-in installed, you can use the following steps to temporarily disable the iManage FileSite add-in. If the hanging problem in Outlook 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.
