Internet Explorer 9 does not open .ica links

If IE9 is saving your .ica links instead of opening the connection here is something to try.

1) Run regedit as administrator
2) Browse to HKEY_CLASSES_ROOT\PROTOCOLS\Filter\application/x-ica
3) Rename application/x-ica to application/x-ica.old
4) Close regedit
Try opening the .ica link now. Hopefully it will open the connection this time instead of saving the .ica file.

Outlook 2007 The messaging interface has returned an unknown error. If the problem persists, restart Outlook.

One thing that I've found that may fix this is if the profile is set to use cached exchange mode uncheck that option. Click Next and then Finish. Restart Outlook.

To get to the setting go to Control Panel>Mail>Email Accounts>on the Email tab double click your email profile. Uncheck the 'Use Cached Exchange Mode' box. Next. Finish. Reopen Outlook.

Keep in mind I am guiding you down the road to no more cached exchange mode. If you want to go back to cached exchange mode you will want to rename the .ost file it was using to .old and recheck the box so it will create a new .ost file.

OST file locations:
Windows 7 and Windows Vista
drive:\Users\user\AppData\Local\Microsoft\Outlook

Windows XP
drive:\Documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook
