How many times you wanted to have Outlook seamless authentication on domain joined computers while connecting to Office 365 like it would do with on premise Exchange? I don't know about you, but I always liked Outlook profile creation without prompting user for entering credentials. This is great feature while Exchange is on-premise since it using either Kerb or NTLM. With moving user mailbox to Office 365, basic authentication for Outlook was only way for authenticating user. Users needed to enter their username / password combination and click 'Save credentials' and everything was fine until user was changed password and prompt would pop up again.
Select the test you want to run. In Microsoft Teams there are two different authentication flows for your app to take advantage of. You can perform a traditional web-based authentication flow in a content page embedded in a tab, a configuration page, or a task module. This article applies to both Office 365 Enterprise and Microsoft 365 Enterprise. Modern Authentication enables Active Directory Authentication Library (ADAL)-based sign-in for Office client apps across different platforms. This enables sign-in features such as Multi-Factor Authentication (MFA), smart card, and certificate-based authentication.

This post will be divided in three parts:
1. Enable modern authentication on Outlook client,
2. Set up intranet sites for STS,
3. Enable Oauth profiles feature in Office 365.
Enable modern authentication on Outlook client
Modern authentication (ADAL) in Outlook 2016 is enabled by default and it will be first mechanism that Outlook will try to use against Office 365. On the other hand, Outlook 2013 has it turned off by default and registry key should be used for enabling it .
Navigate to HKCU:SoftwareMicrosoftOffice15.0CommonIdentity and create new dword value 'EnableADAL' and set it to value '1':
Set up intranet sites for STS
In order to get seamless experience while authenticating to STS, STS should be placed in 'Local Intranet' zone and that zone should have option 'Automatically login with current username and password' option set:
Enable Oauth profiles feature in Office 365
Final step in this process is to enable OAuth2 Client Profile. Open PowerShell session to Office365 tenant and execute following command:
Set-OrganizationConfig -OAuth2ClientProfileEnabled $true
After that wait few minutes and you are all set.
Create new Outlook profile (or wait until profile is automatically switch over to OAuth2) for user that have mailbox hosted in Office 365:
AI: Artificial Intelligence or Automated Idiocy??? One suggestion that may help: Create a Character Style that includes the Hidden attribute & use that rather than applying the attribute directly. When it comes time to generate the PDF either modify the Style temporarily to exclude the Hidden attributeor temporarily apply a different Style that doesn't include Hidden.Another option is to use Advanced Find & Replace to remove the Hidden attribute, but it's much easier & more reliable to reapply it accurately when using Styles. If there is any misunderstanding, please point out.Appreciate your understanding and cooperation.Best regards,Gloria - If you feel a reply works for you, please kindly vote or mark it as it will be beneficial to other community members reading this thread.

You can check in connection status that Outlook is consuming 'Bearer' (fancy name for Oauth) authentication:
How it works? Lets go fiddling..
I won't cover each step Outlook performs while connecting to service (you should know it already!?), just one's that matters. Fire up Fiddler!
1. Client make HTTP POST to https://autodiscover-s.outlook.com/autodiscover/autodiscover.xml
Response: 401 Unauthorized with authorization link https://login.windows.net/common/oauth2/authorize
2. Client submits HTTP GET against login.microsoft.com and request contains user email address:
Request:
Response (redirect to OnPrem STS):
3. STS authenticate client and return it back to login.microsoft.com:

How modern authentication works
Modern authentication is a process that lets Teams know that users have already entered their credentials (like their work email and password) elsewhere, and they shouldn't be required to enter them again to start the app. The experience will vary depending on a couple factors, like if users are working in Windows or on a Mac. It will also vary depending on whether your organization has enabled single-factor authentication or multi-factor authentication (multi-factor authentication usually involves verifying credentials via a phone, providing a unique code, entering a PIN, or presenting a thumbprint). Here's a rundown of each modern authentication scenario.
Windows users

If users have already signed in to other Office apps through their Office 365 Enterprise account, when they start Teams they're taken straight to the app. There's no need for them to enter their credentials.
If users are not signed in to their Office 365 Enterprise account anywhere else, when they start Teams, they're asked to provide either single-factor or multi-factor authentication (SFA or MFA), depending on what your organization has decided they'd like the process to entail.
If users are signed in to a domain-joined computer, when they start Teams, they might be asked to go through one more authentication step, depending on whether your organization opted to require MFA or if their computer already requires MFA to sign in. If their computer already requires MFA to sign in, when they open up Teams, the app automatically starts.
If users are signed in to a domain-joined computer and you don't want their user name pre-populated on the Teams sign-in screen, admins can set the following Windows registry to turn off pre-population of the user name (UPN):
ComputerHKEY_CURRENT_USERSoftwareMicrosoftOfficeTeams
SkipUpnPrefill(REG_DWORD)
0x00000001 (1)Note
Skipping or ignoring user name pre-fill for user names that end in '.local' or '.corp' is on by default, so you don't need to set a registry key to turn these off.
Mac users
When users start Teams, their computer won't be able to pull their credentials from their Office 365 Enterprise account or any of their other Office applications. Instead, they'll see a prompt asking them for SFA or MFA (depending on your organization's settings). Once users enter their credentials, they won't be required to provide them again. From that point on, Teams automatically starts whenever they're working on the same computer.
Switching accounts after completing modern authentication
If users are working on a domain-joined computer (for example, if their tenant has enabled Kerberos), they cannot switch user accounts once they've completed modern authentication. If users are not working on a domain-joined computer, they can switch accounts.
Signing out of Teams after completing modern authentication
To sign out of Teams, users can click their profile picture at the top of the app, and then select Sign out. They can also right-click the app icon in their taskbar, and then select Log out. Once they've sign out of Teams, they need to enter their credentials again to launch the app.
URLs and IP address ranges
Teams requires connectivity to the Internet. To understand endpoints that should be reachable for customers using Teams in Office 365 plans, Government and other clouds, read Office 365 URLs and IP address ranges.
Important
Teams presently requires access (TCP port 443) to the Google ssl.gstatic.com service (https://ssl.gstatic.com) for all users; this is true even if you're not using Gstatic. Teams will remove this requirement soon (early 2020), and we'll update this article accordingly at that time.
Troubleshooting modern authentication
Microsoft Modern Authentication Flow
Modern authentication is available for every organization that uses Teams, so if users are not able to complete the process, there might be something wrong with your domain or your organization's Office 365 Enterprise account.
