There are a shockingly large number of ways to get into a windows PC without the password. For any help to be provided from here we will need some system details:
1. Which version of windows 8, plain 8 or 8.1 , is on the machine
2. Do you have all your personal files on the machine backed up to external media (if you do then reinstall type methods might be ok for you, but if not then you daren't reinstall unless you're happy to lose the files)
3. Are you bothered about the programs installed on the system? That is to say would you be interested in methods of solving this that don't lead to the loss of any personal files but would require you to redo all your system settings and installation of programs after the fix is done?
4. You mention links between a pc and an outlook email address, does this imply that you were using a "connected microsoft account", or were you just using a regular local account
5. Did you ever encrypt the drve with bitlocker or any other similar product? If not then the fix for this will be pretty simple, if you did encrypt then there might be no other option than wiping the machine to a fresh state and reinstalling everything.
6. Can you also provide any other system specifications, they might be helpful.
As for methods of fixing this they could include: password reset discs, wiping and reinstalling windows, other forms of rescue media and certain types of boot CD(I think the forum rules thesedays do allow discussion of these nowadays but I'm no expert on them so can't advise you), live booting from a linux USB and seeing about editing parts of your windows files from there to make logging in possible, some command prompt methods (these could be done on old versions of windows back in Xp days but I don't know whether they can still work on modern more secure systems).
In general however the only methods that are likely to work if your system is encrypted are wiping and reinstalling, also these methods won't get you access to that email again and won't get you access to any sort of connected microsoft account again, but they should probably let you get back into your PC itself.
EDIT:Right now don't worry about any technical terms in my reply above which you didn't quite recognise, just provide more details of your issue and try your best to answer those 6 questions. Someone can then help you later with the steps involved in performing whichever method of fix turns out to be most approproiate to your problem.
