Configure Outlook Desktop¶

The Outlook desktop app provides a richer email experience than the browser and works even when you have limited connectivity. Follow these steps to add your Questcom mailbox.

What you need¶

• Microsoft 365 Apps (Outlook) installed on your Windows laptop
• Your company email (yourname@questcominc.com) and password
• Microsoft Authenticator set up on your phone

Step 1 — Launch Outlook¶

1. Press the Win key and type Outlook.
2. Click Outlook in the search results.

If this is the first time Outlook has been opened, it will jump straight to the account setup screen — skip to Step 3.

Step 2 — Open account settings¶

If Outlook opens to your inbox (or a blank screen):

1. Click File in the top-left menu.
2. Click Add Account.

Step 3 — Enter your email address¶

1. Type yourname@questcominc.com in the email field.
2. Click Connect.

Outlook will detect your Microsoft 365 account automatically.

Step 4 — Sign in¶

1. A Microsoft sign-in window will appear — your email address should already be filled in.
2. Enter your password and click Sign in.
3. Check your phone for a notification from Microsoft Authenticator and tap Approve.

Step 5 — Finish setup¶

1. Outlook will show Account successfully added.
2. Leave Set up Outlook Mobile on my phone too unchecked unless you want the mobile app as well.
3. Click Done.

Step 6 — Wait for your mailbox to sync¶

Outlook will begin downloading your emails. The first sync can take a few minutes depending on mailbox size. You will see a progress bar at the bottom of the screen.

Setting Outlook as your default mail app (recommended)¶

1. Press Win+I to open Settings.
2. Go to Apps > Default apps.
3. Search for Outlook and click it.
4. Set it as the default for Email.

This ensures that clicking a mailto: link in Chrome opens Outlook automatically.
