I can't find the activation code

I got the invitation but I can’t find the activation code for PC, where can I find it?

The code should appear in your Halowaypoint Inbox, if not, check your email.

If you are on Steam, maybe this could help:

I think 343 missed out big time not calling activation codes Index.

Because to activate Halo you need the Index
