Out-of-Office Auto-Reply Risks: What Not to Say Before You Leave

If you run a small business in Monterey County or anywhere on the Central Coast, the holidays mean people are out of the office. Many will set an automatic reply without a second thought. That small courtesy can give a scammer exactly what they need.

This guide explains what an out-of-office message reveals, what to leave out, and a safe template you can paste in today.

1. What your auto-reply tells an attacker

Anyone can email you and read the reply. A criminal does not need to hack anything. They send one message and wait.

• When nobody is watching. Exact dates tell them how long a fake request can sit unchallenged.
• Who is in charge. A line like "contact Maria for invoices" names the person to impersonate or target.
• How to reach you. A mobile number invites a text or voice scam, such as the ones in our posts on fake boss texts and vishing.
• That the account is live. Any reply confirms the address works and is worth targeting.

This is background research for business email compromise. The attack that follows often looks like a rushed request from the owner to a bookkeeper.

2. Write two messages, not one

Microsoft 365 and Google Workspace both let you send a different reply to people inside your company and people outside it. Use that.

• Internal message. Coworkers can get the useful detail: who covers which task and the best way to reach you in a real emergency.
• External message. Customers and strangers get three things only: you are away, roughly when you will reply, and one shared address for urgent matters.
• Limit who gets it. Many systems can send external replies only to known contacts. That stops replies to random senders and spam.
• Turn it off on return. Set an end time when you create the message so it does not run for weeks.

Here is a safe external template: "Thank you for your message. I am out of the office and will reply when I return. For urgent matters, please email team@yourcompany.com." Nothing in it helps an attacker.

3. Back it up with a payment rule

A good message lowers the risk. A good rule removes it. The most expensive scams arrive while the boss is away and the finance person feels pressure to act.

• Call back on changes. Any new bank detail or urgent payment gets confirmed by phone on a known number. See vendor bank detail change fraud.
• Name a backup approver. Staff should never wonder who can say yes while you are gone.
• Protect the account itself. Turn on MFA so a stolen password is not enough, and see our holiday cybersecurity checklist.

The takeaway

An out-of-office message should say less, not more. Keep dates and places private, split inside and outside versions, point to a shared address, and back it with a call-back rule for money. It takes ten minutes and costs nothing. For help setting this up for your team, see our cybersecurity and managed IT services, or check current pricing.

Frequently asked questions

Is it safe to put my travel dates in an out-of-office message?

Keep dates vague. Say you are away and will reply when you return, not where you are or the exact days. Travel details tell scammers when nobody is watching your accounts.

Should I use different out-of-office messages for internal and external senders?

Yes. Both Microsoft 365 and Google Workspace let you write one message for coworkers and another for outside senders. Put the detail inside, and keep the outside message short.

Can an out-of-office reply be used for phishing?

Yes. Attackers send a test email, read the reply for names, titles, phone numbers and dates, then craft a believable request to your staff or vendors while you are away.

What should an out-of-office message include?

Say you are away, when you will respond, and give one shared team address for urgent matters. Leave out your title chain, mobile number, location and the names of coworkers who approve payments.

Do I need an auto-reply if I am just out for a few hours?

Usually not. Use one for a full day or longer. Short gaps do not need a reply, and every automatic message gives outsiders a little more information.
