Outlook Basic Operations: Sending Email, Importance Levels, and Formatting

If you’re planning to run a fashion label, a boutique, or a garment export business, email is going to be your most-used tool for talking to suppliers, buyers, and customers. Microsoft Outlook remains one of the most widely used email clients for business communication, and knowing its basic operations well can save you time and prevent embarrassing mistakes. This post covers the core Outlook tasks every professional should know: sending a message correctly, marking it with the right importance level, formatting it so it reads well, adding a signature, and attaching files.

Composing and sending your first email 🔗

Sending an email is, unsurprisingly, the task you’ll perform most often in Outlook. To start a new message, go to the File menu, point to New, and click Mail Message. This opens a blank message window with all the fields you need to fill in before your email is ready to go out.

Filling in the recipient fields 🔗

Every email needs at least one recipient in the To field, which is meant for the primary person or people you’re writing to. The Cc field, short for carbon copy, is for people you want to keep informed but who aren’t the main recipient. Then there’s Bcc, or blind carbon copy, which sends a copy to someone without the other recipients knowing they received it. This is useful when you want a colleague or manager to see a client email without making that visible to the client. If you’re addressing more than one person in any of these fields, separate the addresses with a semicolon.

Writing the subject and message body 🔗

Once your recipients are set, add a clear subject line and type your message in the body. A vague or missing subject line often means your email gets buried or ignored, especially when you’re reaching out to a busy supplier or buyer for the first time. After you’ve written and reviewed your message, click Send. According to Microsoft’s own guidance on composing messages, you can send the same email to one or more recipients in a single go, which makes it easy to loop in multiple vendors or team members at once.

Setting the importance level of a message 🔗

Not every email carries the same weight. Some need immediate attention, like a payment confirmation deadline, while others are just informational updates. Outlook lets you flag this using importance levels.

How to mark a message High or Low importance 🔗

With your message open, go to the Message tab and look in the Options group. Here you’ll find two buttons: High Importance and Low Importance. Clicking one of these adds a visual marker that recipients see in their inbox. Microsoft describes this as a way to let people know your message needs urgent attention, or alternatively, that it’s a low-priority FYI they can look at whenever convenient. Recipients can also sort their inbox by importance, which helps them triage a full inbox quickly.

What importance really means for delivery 🔗

It’s worth understanding what this feature does and doesn’t do. Setting High Importance does not make your email travel faster across the internet or arrive sooner in someone’s inbox. It’s purely a signal to the recipient about how urgently the content should be treated, not a technical priority setting for transmission. So while it’s a handy way to flag genuinely urgent matters, like a last-minute change to a purchase order, overusing it dilutes its usefulness. If every email you send is marked High Importance, recipients will eventually stop paying attention to the flag altogether.

Changing the appearance of your email 🔗

How your email looks affects how it’s read. A wall of unformatted text is harder to skim than a message with a bolded deadline or a highlighted key figure.

Using the Basic Text and Font groups 🔗

Outlook gives you two main places to format text: the Basic Text group on the Message tab, and the more detailed Font group on the Format tab. From here, you can change the font, adjust font size, apply bold, italic, or underline styles, change font colour, and highlight text. If you’re sending a quotation to a buyer, for instance, bolding the total price or highlighting a delivery date helps it stand out instead of getting lost in a paragraph.

The Mini toolbar and Format Painter 🔗

When you select any text in the message body, a small floating Mini toolbar appears near your cursor. This gives you quick access to common formatting options and theme selection without needing to move your cursor all the way up to the ribbon. Outlook also includes a Format Painter tool, which lets you copy formatting from one piece of text and apply it to another, useful when you want consistent styling across a longer email. As one Microsoft Office reference guide puts it, you can format the text and background of your messages either by choosing individual styles or by applying a ready-made theme, which is a quick way to keep your emails looking polished without manually setting every detail.

Adding a signature to your emails 🔗

A signature saves you from retyping your name, designation, and contact details every time you write an email, and it also gives your messages a more professional, consistent look, something that matters when you’re building a brand identity for your label or store.

Setting up a default signature 🔗

To create one, go to the Message tab, and in the Include group, click Signature, then Signatures. This opens a dialog box where you can create a new signature, name it, and type out the text you want included, such as your name, job title, business name, and phone number. From here, you can also set this signature as the default for all new messages, as well as for replies and forwards. As official guidance on Outlook signatures explains, you can even use a different email account with a different signature if you manage more than one inbox, say, a general enquiries address and a separate one for supplier communication.

Adding a signature manually 🔗

If you haven’t set a default, or want to use a different signature for a specific message, you can add one manually. With a message open, click the Signature button in the Include group and choose the signature you want from the list. This is handy when you occasionally need a shorter signature for internal team emails and a fuller one with your business address for client-facing communication.

Attaching files to your email 🔗

Whether it’s a product catalogue, a spec sheet, or an invoice, attaching files correctly is a basic but essential Outlook skill.

How to attach a file 🔗

On the Message tab, in the Include group, click Attach File. Browse to the location where your file is saved, select it, and click Insert. The file becomes part of the email and is delivered to every recipient when you hit Send. Microsoft’s documentation on attachments also notes that you can drag and drop a file directly into the message window as a quicker alternative to browsing through folders.

Things to keep in mind before attaching 🔗

Large attachments can bounce back or take a long time to send, particularly over a slower connection, so it helps to compress bulky files like high-resolution lookbooks or design portfolios before sending them. It’s also worth double-checking that you’ve attached the correct version of a file, especially when you’re sending revised price lists or updated purchase orders to a supplier, since sending an outdated attachment can lead to confusing or costly mix-ups.

What do you think? Which of these features do you think would make the biggest difference in how professional your business emails come across: the formatting options, the signature, or knowing when to actually use High Importance? And have you ever sent an email without an attachment you meant to include?
