Unexpected Account Lock Out on Logging to Outlook

In last 4 - 5 months, my account in office domain was kept locked out periodically. I tried my best to investigate the root cause, so I was patience in asking our system admin to keep unlocking my account while I was investigating it.
There are many possible reasons for account lock out. The first thing, of course don't enter wrong passwords 3 times in a row (no. of times depends on your domain setting). Checked. Secondly, you have to make sure that you don't tick 'Save password' option in any areas. Checked.
Third, you have to make sure that you don't have mapped network drive. Checked.
So ... up to this stage I was confused ... what else could be wrong? After some times, I noticed that each time I logged into Outlook, my account was locked out. Well ... at least I've found the starting point to start the deeper investigation with. Browsing here and there, I found Knowledge Base about the possible reasons for that. In my case, the reason is because I have many accounts in different domains with same name. So what did I do? I removed the domain in my computer (by joining to Workgroup instead, in Control Panel>System>Computer Name), and then log in to local with different name.
Thank God ... so far it has never been locked out ... Otherwise, I might need to change my real name!
