Set up an out of Office Auto-Reply

While you are away from the computer, Outlook can automatically reply to incoming mail with a message telling senders when you’ll be able to reply individually.

Create an Email Signature in Outlook

Set up a short piece of text containing essential contact information, a tag line, or maybe an ad or quotation and insert this information in every email you send from Outlook. If you use several email accounts with Outlook, create several email signatures.

Insert a Graphic or Animation in Your Outlook Email Signature

Create a signature that appends to your outgoing emails in Outlook and makes it a richer experience by adding graphics, animations, and logos.

Send an Email to Undisclosed Recipients

If you want to send an email to a group of people but keep their email addresses hidden, send it to “Undisclosed recipients” in Outlook.

Prevent Outlook From Sending Winmail.dat Attachments

Winmail.dat is a proprietary Windows format for attachments that leverages the .dat file generic encoding. If your Outlook program sends attachments as Winmail.dat, it could confuse and concern recipients. Configure Outlook to make sure it does not send winmail.dat attachments to mail recipients.

Insert an Inline Image in an Email

You can include your photos, sketches, or other images in the body of your email messages instead of as attachments. These graphics are called in-line images and automatically display in the body of an email message.

Access Your Outlook.com or Hotmail Email

Use Microsoft Outlook to fetch and send email messages through your Hotmail or Outlook.com account easily and with all the power and flexibility of a desktop email client.

Change the Default Email Font and Size

Is the font Outlook uses when you compose a message or read an email too wide, tall, small, big, or blue? Specify the precise font, style, and color to use by default for emails in Outlook.

Increase the Font Size While Reading Mail in Outlook

Is the small font used in emails too difficult for you to read? Increase the size of the text in your email messages in Outlook.

Add a Background Image to a Message

Give your emails a colorful and original background in Outlook. Some recipients may not see this background if their email program is configured to not download or display images or special designs from the internet.

Add Blind Copy (Bcc) Recipients

Blind carbon copies are used to send copies of the message to multiple recipients without disclosing some of those recipients. This technique lets you send emails to many recipients without showing their names or email addresses to everyone else the message is sent to.

Sync Google and iPhone Calendars With Outlook

Integrate your Google or iPhone Calendar with your Outlook information. Set them up to sync with your Outlook calendar so all of your devices show the same events and appointments.

Set up a Distribution List in Outlook

Create your own mailing lists in Outlook and easily send messages to groups of people. A do-it-yourself list works great for home users who don’t have access to a corporate distribution list.

Backup or Copy Your Outlook Mail, Contacts, and Other Data

If your email, contacts, and calendars are in Outlook, create a backup of that information to make sure you don’t lose it if your hard drive crashes or Outlook stops working. Create backup copies of your Personal Folders (.pst) files — the files where this information is saved. Creating a backup is as easy as copying the file to a second location.

Set the Default Account in Outlook

When you start a new message in Outlook, the default account is the one that automatically determines which settings — the signature and the sending email address, for example — will be used. Set the default account when you have more than one account connected to Outlook.

Set the Default Message Format

You don’t have to choose your favorite message format every time you create a new message. Make your favorite settings your default in Outlook.

Automatically Cc: All Mail You Send

If you have an email account that you use to back up your messages, or if you need to copy someone on every message you send, Outlook can automatically send a carbon copy of every message you compose to another email address.

Increase the Outlook Attachment Size Limit

If you send a message with an attachment and Outlook won’t let you send it because the attachment exceeds some limit, adjust the Outlook attachment size limit. Set the limit to match that of your email server so emails don’t bounce back as undeliverable. Making this change helps avoid unnecessary Outlook errors, too.

Export Your Outlook Contacts to a CSV File

Keep your contacts even if you leave Outlook behind. If you save your Outlook contacts as a CSV file, you can easily import them elsewhere.

Import Contacts From Excel or a CSV File Into Outlook

It only takes a few steps to import contacts into Outlook. Then you can use those contacts to build the basis for a mailing list, for example. Outlook supports imports if the underlying file is a supported type, like a CSV document.

Set up an All Mail Folder

The search capabilities in Outlook make it easy to find a message when you need it. Creating an All Mail folder for all your messages makes it even easier — it’s a great way to create a unified inbox in Outlook.

Schedule Emails in Outlook

Tell Outlook to deliver a message on or after a certain date. Delayed sending is great for reminders, birthday wishes, and similar items you plan today but won’t send until some future date.

View the Complete Message Source

Make Outlook retain the original message source when it retrieves emails from the internet. Full headers are useful when troubleshooting a problem or if you need to prove some fact about the receipt of a message.

Edit a Received Message in Outlook

Outlook makes editing received emails easy. Use this technique to adjust subject lines and other important information.

Forward an Email as an Attachment

Forward the full email and in the state in which you received it as an EML attachment in Outlook. This preserves all the metadata of the original message, which is useful especially in troubleshooting or legal contexts.

Separate Email Recipients With Commas

Use commas to separate multiple email recipients in a message. By default, Outlook uses semicolons, but you can change the divider to commas if you wish.

Quickly Find All Mail From a Specific Sender

Unless you have permanently deleted a message, Outlook retains all the messages from a particular sender in a folder. Use this feature to quickly find them for reference.

Delete an Address From the Outlook Auto-Complete List

If Outlook remembers an email address you mistyped or if you want to get rid of an outdated name, clear unwanted entries from the auto-complete list that appears when you type an email address in the To field.

Restore an Outlook PST File for Mail, Contacts, and Data

Automatically Filter One Sender’s Mail to a Specific Folder

If you receive emails from a specific sender that you need to file away for future reference, set up Outlook to send those messages to a specific folder as soon as they are received. Start with a message, then set up an Outlook filter to automatically move all of the sender’s future emails to a particular folder.

Change the Way Unread Messages are Highlighted

When you want unread messages to stand out, highlight unread mail in Outlook using special fonts, colors, and more.

Attach a File in Outlook

When you want to send a file along with your email using Microsoft Outlook, attach the file to the email message.

Purge Deleted Messages
