If you work in an industry (like PR, for example) where clients expect a response in a matter of moments or hours, you may need to set an out-of-office message if you’re absent for an afternoon. If you’re not sure whether you should set one, ask your boss or a coworker or consult your employee handbook.
With plenty of employees still working remotely months into the pandemic, “I actually think it’s more important now than it was before,” says Muse career coach Angela Smith. “From the perspective of how do we make remote work work,” she says, “overcommunication is one of the hallmarks.” In a world where you can’t see whether your colleagues are at their desks, being clear about when you’re working—and when you’re not—is crucial to keeping things running smoothly.

I worked with a guy years ago who would update his voicemail greeting literally every time he left the office. So the bare minimum would be that he’d record a new message when he arrived in the office in the morning. Then, when leaving for lunch he’d record a new greeting listing the time he would be back in the office, then he’d record a new message when he got back from lunch, then a new one at the end of the day saying he would be back in the morning. That’s not even counting the times he was out of the office on work business. It was deranged, especially since he had the type of job where he would normally be in and out of the office often.
Note: Outlook does not attach your signature when it sends automatic replies. If you have a signature, you might want to paste it below your message. If you don’t have one, learn how to add an email signature in Outlook.
