Exchange 2010 Management Console And IE9 Issue…

Error while closing EMC 2010

A quick google says that many others are having the same issue and that it happens when the box that has EMC loaded has IE9 as well. I checked my test machine and it had IE9 as well. I uninstalled IE9 and things are fine now. As Microsoft is aware of the issue, there should be an update to fix this issue soon. The workaround is to uninstall IE9 or kill mmc from task manager for the time being.

Anyone else having the same issue? Any other workarounds?

    What worked for me was turning off "Internet Explorer Enhanced Security Configuration" for Administrators and Users and then adding https://localhost to the "trusted sites" in IE Security as well.

    Close EMC, and all IE windows and reopen EMC and I have not been prompted with "you must close……….." from EMC since.
