Follow these steps to install Microsoft Outlook from the Mac App Store, sign in with your Microsoft 365 account, and optionally add any shared mailboxes your organisation uses.
You'll need your Microsoft 365 work email address, your password, and your phone nearby for two-factor authentication. You'll also need an Apple ID to download Outlook from the Mac App Store. If Microsoft 365 was set up for you by Hello Computer, Outlook may already be installed — check your Applications folder first.
Open Finder, then click Applications in the sidebar. Scroll through the list or use the search icon to look for Microsoft Outlook.
If it's already there, double-click to open it and skip ahead to Step 3. If not, continue to the next step to install it from the Mac App Store.
Open the App Store on your Mac (it's in your Applications folder or Dock). Search for "Microsoft Outlook" and look for the app by Microsoft Corporation.
Click Get, then authenticate with your Apple ID to download and install it. Once installed, Outlook will appear in your Applications folder and Dock.
Open Microsoft Outlook from your Applications folder or Dock. The first time it opens, a welcome screen will appear. Click Add Account.
Enter your work email address — for example, jane.smith@yourcompany.com.au — and click Continue. Outlook will detect that this is a Microsoft 365 account.
A Microsoft sign-in window will open in Outlook. Enter your email address (it may already be pre-filled), click Next, then enter your password and click Sign in.
If your organisation has two-factor authentication enabled, you'll need to approve the sign-in via the Microsoft Authenticator app on your phone, or enter a code sent by SMS. Follow the on-screen prompts to complete verification.
After signing in, Outlook will configure your account and sync your emails, calendar, and contacts. This initial sync may take a few minutes.
Your emails will appear in the Inbox in the centre panel. Use the left-hand sidebar to navigate between Mail, Calendar, Contacts, and Tasks.
If your organisation has granted you access to a shared mailbox, you can add it to Outlook for Mac so it appears alongside your personal inbox. Your IT administrator must first grant you Full Access permission in Microsoft 365.
In Outlook for Mac, click Tools in the menu bar at the top of your screen, then click Accounts. The Accounts panel will open.
In the Accounts panel, click the + (plus) button in the bottom-left corner, then select Open Shared Mailbox… from the menu that appears.
A dialog box will appear asking for the shared mailbox address. Type the full shared mailbox email — for example, reception@yourcompany.com.au — and click Open.
Because Full Access permission has already been granted by your IT administrator, Outlook will open the shared mailbox without asking for a password.
The shared mailbox will appear in Outlook's left-hand folder pane, below your personal inbox, as a separate account with its own Inbox, Sent Items, and Drafts folders.
To send email from the shared mailbox, click New Message, then click the From field and select the shared mailbox address. The recipient will see the shared address as the sender.
If you get stuck at any point, our team is happy to walk you through the setup over the phone or via remote support.
