Install Outlook for Mac

Before starting, ensure that your device is on macOS® v 10.10 or later, because this is a requirement to use Office for Mac 2016.

When you install Outlook for Mac, there are two options: a company or personal product key or an Office 365 license that
includes a downloadable version of the Office Suite.

If you have a company or personal product key, navigate to the link below, select the appropriate language, and then select Download:

1. After the download has completed, open Finder > Downloads and double-click Microsoft_Office_2016_Installer.pkg.

2. On the first installation screen, select Continue to begin the installation process.

3. When prompted, enter your Mac login credentials to complete the installation process.

4. Finally, enter your product key.

If you have an Office 365 license which includes a downloadable version of the Office Suite, use the following steps:

Note: If you aren't sure if your license includes the Office suite, contact your administrator.

1. In a web browser, navigate to office.com. Click Sign-In and enter your Office 365 email address and password.

2. After you sign in, navigate to Settings and then Office 365 Settings > Software

3. On the Software page, select Install under Install Office 2016 for Mac to begin the download.

4. After the download completes, open Finder > Downloads and double-click Microsoft_Office_2016_Installer.pkg.

5. On the first installation screen, select Continue to begin the installation process.

6. When prompted, enter your Mac login password to complete the installation.

Configure your Office 365 mailbox for use with the Outlook for Mac desktop client

Use the following steps to set up your Office 365 mailbox within the Outlook for Mac desktop client:

1. Start Outlook for Mac.

2. Under the Tools menu, select Accounts.

3. Click the + sign in the lower-left corner, and then select New Account

4. Enter your Office 365 email address when prompted, then select Continue

5. Finally, enter your Office 365 mailbox password when prompted to complete the setup process.

Troubleshooting

If you have previously configured your Office 365 mailbox for use in the Outlook for Mac desktop client, yet you
continue to receive password prompts, use the following steps:

1. To verify your credentials, attempt to log in at office.com with your Office 365 email address and password.

2. Clear old entries from the Keychain Access for Mac, because Outlook might be trying to authenticate with
   an old password. For more information, see (Clear keychain access for Mac)[/support/how-to/clear-keychain-access-for-mac].

If you are unable to connect to the server, use the following steps:

1. Verify that you have a functioning network connection.

2. Verify that autodiscover has been configured correctly for your domain. For more information, see (Create DNS records using Windows-based DNS)[https://docs.microsoft.com/en-us/microsoft-365/admin/dns/create-dns-records-using-windows-based-dns?view=o365-worldwide].

3. Contact your administrator to see if multi-factor authentication has been enabled for your organization.
