Edit /etc/gdm/custom.conf and add this to the file. You could use gedit or vi whatever suits you, but you need to do it as root.
[daemon]
TimedLoginEnable=true
AutomaticLoginEnable=true
AutomaticLogin=username
TimedLogin=username
TimedLoginDelay=0

Obviously you would replace “username” above with the actually “username” you wish to login automatically.

Now reboot and test it!

1. Quit Outlook.
2. Click Start, click Run, type regedit, and then click OK.
3. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins\
   You should be able to see all the addins for outlook. Just find the one you want.
4. Right-click LoadBehavior, and then click Modify.
5. In the Value data box, type 1, and then click OK.
6. Quit Registry Editor.
7. Start Outlook and the addin shouldn’t load.

It might be a good idea to take a back of your registry or make a system restore point before doing this – just in case you make a mistake or something goes wrong.
