A blocked senders list for what? Generally, if you want to block a sender in Outlook, it's because they repeatedly send you email that you don't want.
If you're thinking of a spam blocker, then no. Spammers generally make up new fake email addresses and domain names every time they send a message so blocking one won't block the next one. The only effective way to block email spam is by contents of the message and suspicious activity, and no pre-made list can do that. Either that or block all email from everyone and only allow (white list) the people that you actually want to communicate with.
