Once Hogwarts Legacy players choose their house and get familiarized with the many hallways and corridors of the Hogwarts castle, they'll eventually notice that many of the mechanics and features within the main menu are blocked off. Unlocking the Owl Post and other stuff like Talents won't happen until wizards and witches get farther into the main storyline.
What's the Owl Post?
Hogwarts Legacy players will befriend all sorts of people around Hogwarts, and sometimes, these NPCs can send players Owl Posts, which can be opened by heading into the Field Guide and tabbing over to the Owl Post section, which is right in-between 'Quests' and 'Settings.' These posts will come with requests and/or updates from friends or professors, either telling players to meet them somewhere to start a new quest or to just check-in with them, like friends do.
When Can I Get Owl Posts?
Hogwarts Legacy players will get introduced to the Owl Post functionality soon after they beat the troll in the first Hogsmeade mission with Natty or Sebastian, depending on which character players chose to hang out with. The first person that will send players an Owl Post will none other than Professor Fig. The game will prompt players to open the Owl Post with a click of the left control stick, which is L3 on PS4/PS5. This will allow you to check out your mail without having to dig into the menus, making it much faster.
So far, it seems that players don't have to worry too much about checking Owl Posts, as notifications will appear on-screen whenever players get a new letter. Reading text in a menu might not be as exciting as receiving an actual letter from one of the iconic owls of Harry Potter lore, but it's still a neat feature that will keep players occupied with side quests and other activities.
Some players might've noticed that there is indeed a post office in Hogsmeade to walk into, but it seems that the NPC attendant inside cannot be spoken to. While it may seem that this is a way to send other NPCs letters, as of the time of writing, the post office has no use other than to explore.
Hogwarts Legacy is out now for PC, PS5, and Xbox Series X/S. It's in development for PS4, Xbox One, and Switch.
