What Is an Out‑of‑Office Message in Modern Support Operations?

TL;DR: An out‑of‑office (OOO) message is an automated response that informs people when you’re unavailable, what to expect next, and how to get help if needed. This guide explains what OOO messages are, why they matter, and when they should be used to ensure clear communication and uninterrupted workflows.

Sometimes you need to step away from work—whether it’s for vacation, travel, training, or a personal appointment.

Whether you can check your email inbox or not, an out-of-office message lets anyone contacting you know of your unavailability.

It shows respect for customers and coworkers by setting expectations, even when you’re away.

We will discuss how to write the perfect out-of-office message, including how you can set it up.

What is an out of office message?

An out-of-office message is an email sent automatically to inform anyone reaching out to you that you are not in the office and unable to respond immediately. It is also commonly referred to as an OOO message or an out-of-office email.

Use an out-of-office message anytime you can’t respond as usual—whether you’ll be away for a few hours, a day, a week, or longer.

With this message, you do not have to deal with unhappy customers or colleagues who were unaware of your absence; instead, it informs them of your inability to respond at the time and provides an alternative contact person or team.

When to use an out-of-office message and its importance

Customers value fast responses, especially when they need help. When a support agent is unavailable, an OOO message helps set the right expectations and maintains a positive customer experience.

Up to 90% of customers cite immediate responses as a key metric for their satisfaction.

The following are some common types of OOO messages.

• Short and simple
• Formal out of office message
• Business trip
• Vacation
• General leave of absence

Just like canned responses and saved email templates, out of office messages are increasingly becoming a necessity.

An out of office message is important because it:

• Streamlines communication: It provides information about your absence, when you’ll be back, and an alternate contact person for emergencies. Effective communication reduces the number of unhappy customers due to delayed responses.
• Drives engagement: It is possible to include links to your social media sites, products, updates, and information in your OOO message. This makes it easier for people to reach out to you, which ultimately boosts engagement and drives traffic to your business.

How to write an out of office message

Drafting an out of office message is simple and quick. These are tips that you should always consider when writing an OOO message:

• Short, clear, and concise messages: To maintain clarity, keep your out-of-office messages brief and direct to the point. They should be between 3 and 6 sentences. It should be something like this:

• Professional and unique tone: Showcase your brand personality while being professional in your out of office message. It personalizes the message, making it sound trustworthy. Always start with a warm greeting, thank the sender, and sign off politely. Consider this as a possible example:

What to include in an out of the office email message

Writing a standard out-of-office message can be confusing, especially when you don’t know the essential information to include.

Consider the following tips for your out of office email to make it refined and exciting:

• Subject line: Always start the OOO email with an attractive, clear, short, and direct subject line for anyone reaching out to know that you’re out of the office. It can sound like: ‘Out of office on leave,’ ‘Out of office alert!’
• Greetings: Include a brief salutation to set the tone for your OOO message, ensuring it sounds professional and polite. Examples of these greetings include ‘Hello’ and ‘Hi’.
• Provide an alternative communication means: Make sure to include alternate contact options. These could be an email, phone number, and physical address.
• When you’ll be out and back: Include dates for the duration you will be away and back to the office. This is for planning purposes.
• Professional sign-off: End your OOO message professionally by including your name, position held at the company, signature, and any other relevant information that can be included.
• Necessary information: Include a message acknowledging receipt of the message, what recipients should expect, and inform them that it is an automatic reply.

Common mistakes to avoid when writing out-of-office messages

An out‑of‑office (OOO) message may seem simple, but when written poorly, it can create confusion, delay support, or negatively impact the customer experience.

To ensure your OOO message remains clear, professional, and customer‑friendly, avoid the common mistakes outlined below.

Oversharing personal information

While it’s helpful to explain your absence, sharing too much personal detail is unnecessary and unprofessional.

What to do instead:
Keep your message short and neutral. A simple statement such as:

“I’m currently out of the office on a business trip.”
is more than sufficient and keeps the focus on customer support.

Forgetting to activate your out‑of‑office message

Failing to enable your OOO autoresponder can leave customers waiting without any acknowledgment.

What to do instead:
Always activate your out‑of‑office message before stepping away, especially if you handle customer queries or support tickets.

This reassures customers that their message has been received.

Including unclear or incorrect information

Incorrect return dates or outdated contact details can frustrate customers and slow down issue resolution.

What to do instead:
Before activating your OOO message, double‑check:

• Your return date
• Alternate support contact details
• Business hours (if included)

Accuracy helps customers know exactly what to expect.

Skipping proofreading

Spelling mistakes, grammar errors, or unclear sentences can make your message appear rushed or careless.

What to do instead:
Take a moment to proofread your OOO message. A well‑written response reflects professionalism and builds trust with customers.

Using excessively informal language

Overly casual or playful language may give the wrong impression, especially in customer support or service roles.

What to do instead:
Maintain a polite, professional, and friendly tone. Avoid slang or excessive humor unless it aligns clearly with your brand’s support voice.

Catchy subject lines to use in your out of office messages

Easily capture your reader’s attention with a simple and elegant subject line for your autoresponder. Here are some simple subject line examples:

• Out of office alert!
• Thanks for reaching out
• Out of the office temporarily. Back on [Return Date]
• On leave. Thanks for understanding
• Away on a much-needed break
• Sorry for the inconvenience caused
• Currently taking some time off, sorry!
• Out-of-office, but while I have you here…

Common out of office scenarios where support teams fall behind

Out‑of‑office messages help customer support teams set clear expectations when agents are unavailable. They reduce confusion and reassure customers that their message has been received.

Support teams rely on OOO messages during vacations, leave, travel, after‑hours requests, or short absences. While the tone may vary, the goal is the same—keeping customers informed and supported.

Here are the common scenarios where support teams use out‑of‑office messages.

Scenario 1 – Support after work hours

When customers contact support outside normal working hours, OOO messages explain that the team is currently unavailable. They also share when support will be back online and when a response can be expected.

Scenario 2 – Weekend support unavailable

This scenario applies when customers reach out on weekends. OOO messages let them know support responses may be delayed and confirm when weekday support will resume.

Scenario 3 – Support closed for holidays

During public holidays or company‑wide breaks, OOO messages inform customers that the support team is closed. They clearly mention the reopening date or alternate help options if available.

Scenario 4 – Support agent on leave

When a specific support agent is on leave, OOO messages notify customers about the absence. They guide customers to another agent or a shared support channel for help.

Scenario 5 – Agent shifts not active

For teams working in shifts, OOO messages are used when an agent’s shift has ended. They help customers understand that another agent will reply during the next active shift.

Scenario 6 – Live chat temporarily unavailable

When live chat is offline or agents are busy, away messages inform customers that chat support is unavailable. Customers are guided to submit a ticket or try again later.

Scenario 7 – Urgent issues and emergency support

In urgent situations, OOO messages direct customers to emergencies or priority support channels. This ensures critical issues are handled without delay.

Scenario 8 – Delays due to high support volume

When support teams receive a high number of requests, OOO messages explain response delays. They reassure customers that their request is in the queue and will be answered soon.

To help you respond clearly in every situation, here are proven out‑of‑office message templates for each scenario.

How to set up out-of-office messages

It may sound like a lot of work, but it’s a relatively simple process that should not take more than three minutes.

Here is how you can easily set up out-of-office messages using your preferred mail service provider:

Set up out‑of‑office messages in BoldDesk

BoldDesk doesn’t use a single “Vacation responder” toggle like Gmail. Instead, out‑of‑office messages are handled through agent availability and automated offline replies, which gives support teams more control over routing and customer expectations.

Option 1: Set an agent status as “Out of Office” (recommended for leave or vacations)

This prevents new tickets from being assigned to the agent while they’re away.

1. Go to Admin → Agent Availability Status.
2. Select the agent who will be out of office.
3. Change the agent’s status to Offline for the duration of the absence.
4. Save the changes.

Once set, BoldDesk stops assigning new tickets to that agent, ensuring customers are routed to active team members instead.

Option 2: Send automatic OOO replies using Offline Messages (after hours or unavailable)

Offline messages automatically notify customers when support is unavailable.

1. Go to Admin → Chat → Business Hours and set your working hours.
2. Navigate to Admin → Chat → Channel Settings (WhatsApp, SMS, or Live Chat).
3. Enable Offline Message.
4. Enter your out‑of‑office message explaining the delay and next steps.
5. Click Save.

Customers who contact support outside business hours will receive the OOO message automatically.

Option 3: Auto‑reply for tickets using automation (advanced)

For email or ticket‑based OOO replies:

1. Go to Admin → Automation → Ticket Automation.
2. Create a rule triggered on ticket creation.
3. Add the Add Reply action with your out‑of‑office message.
4. Activate the rule.

This is useful for high‑volume queues or shared inboxes.

Set up out‑of‑office messages in Gmail

Gmail makes this pretty straightforward, but the setting lives in the main Settings menu (not inside a separate “Auto-reply” screen), so it’s easy to miss.

• From your inbox, click the gear iconto open Settings.
• Select See all settings.
• Under the Generaltab, scroll down until you find Vacation responder.
• Turn it On, paste your out-of-office message, confirm your subject lineand start/end dates, then click Save Changes.

Set up out‑of‑office messages in Outlook

Outlook’s layout varies by version (classic Outlook, new Outlook, Mac, web), but the setup usually follows the same pattern: open settings, enable automatic replies, choose a time range, and paste your message.

• Open Outlook and go to File(or Settings, depending on your version).
• Select Automatic Replies(sometimes shown as Out of Office).
• Turn automatic replies on, set your startand end date/time, then paste your message.

• Open iCloud Mail settings(often via iCloud on the web).
• Find Auto-reply / automatic response
• Turn it On, set your date range, and paste your out-of-office message.
• Save your changes.

An email auto-reply is helpful—but if your team works in Teams all day, setting your Teams status message can reduce follow-ups and pings while you’re away.

• Open Microsoft Teams.
• Go to your profileand open your status settings.
• Choose Out of office, set the schedule(start/end), and add a short status message (optional but recommended).
• Save to activate it.

Always be professional and reliable with an out of office message

Whether you’re away from the office for a short or long period, it is important to remain professional by communicating adequately.

An out-of-office message lets whoever tries reaching out know you are away, so you won’t have to worry.

This avoids hurting your relationship with customers and colleagues by providing information and how to move forward despite being absent.

Clear communication is easier when your help desk can automate replies, route tickets, and track SLAs so customers aren’t left waiting.
