The last few days I have been getting this error message when I try to close the Exchange 2010 Management Console:
“You must close all dialog boxes before you can close Exchange Management Console”.
After working Google a bit and going over logs I found out that it started after the installation of IE9.
There are three things that I can do as Microsoft haven’t fixed this yet
- Add https://localhost to Trusted sites in IE9 Security (enough for me)
- Turn of “Internet Explorer Enhanced Security Configuration” for Admins and Users
- If all fails, simply uninstall IE9
After I did nr:1 above I closed EMC and IE9 and I haven’t been prompted since.
