Unable to relaunch MS Outlook after closing down without rebooting the computer
If you have Norton 360 and if you have problem in relaunching MS Outlook without rebooting the computer you can follow the steps listed below.
1. Open Norton 360.
2. Click on Settings.
3. Click Quick Controls -> Uncheck “SymProtect Tamper Protection”
4. Close Norton 360
5. Click Start and click Run.
6. In the Run dialog box, Type the following command and click Ok
Regsvr32.exe /u “C:\Program Files\Norton 360\tpShell.dll”
After performing the above steps please check whether the issue is resolved. If the issue still persist then
1. Click Start and click Run.
2. Type the following command and click Ok
Regsvr32.exe /u “C:\Program Files\Common Files\Symantec
Shared\Backup\buShell.dll”
Now your issue will be completely resolved.
After this make sure you have re-enable Symprotect Tamper Protection without fail.
Cause for this problem is due to the OUTLOOK.EXE process running at the background even after we close the MS Outlook.
As a work around you can also try relaunching MS Outlook after ending the OUTLOOK.EXE process from the task manager. (To open task manager press Ctrl+Alt+Del at the same time)
