Setting Up Automatic Replies in Outlook the Right Way
Out of office replies do more than most people realize, once you know where to look.

Most people right click their calendar, turn on "Out of Office," type one line, and move on. That works, but Outlook's automatic replies can do a lot more than a single canned message, and most of it is hiding in settings people never open.
Two messages, not one
Automatic Replies lets you write a different message for people inside your organization than for people outside it. Go to File, Automatic Replies, and you'll see two tabs: "Inside My Organization" and "Outside My Organization." Use the internal one for details your coworkers need, who's covering for you, when you'll check email. Use the external one for something shorter and more guarded. By default the external reply is off, so you may be sending nothing to clients or vendors while colleagues get the full note. Check that box if you want customers to know you're out.
Scheduling it in advance
You don't have to remember to turn this off. Under "Send replies only during this time period," set a start and end date and Outlook handles it for you, including switching back on the day you return. This matters more than it sounds, forgetting to disable an out of office message is one of the most common small embarrassments in an inbox.
Rules, not just replies
The same dialog has a "Rules" button most people never click. From there you can forward mail to a colleague while you're away, flag anything from a specific sender, or move newsletters straight to a folder so your inbox doesn't pile up while you're gone. It runs alongside your regular Outlook rules, so nothing conflicts.
A quirk worth knowing
Automatic Replies only sends once per sender for the whole period it's active, not once per email. If someone emails you five times while you're out, they get the reply once. That's normal, not a bug, and it's why people sometimes think their out of office isn't working when it actually is.
If you use Outlook on the web instead of desktop, the same settings live under Settings, Mail, Automatic replies, with the same two tabs and the same rules option.
