Using the New Outlook for Mac features in business environments
For security reasons, the password cannot be viewed from your Outlook profile or retrieved from an existing browser session.
To add the account to New Outlook for Mac, please refer to Add an email account to Outlook for Mac and sign in using your account credentials.
If your organization supports alternative sign-in methods, such as passwordless authentication, you may be able to select Sign-in options during the sign-in process instead of entering a password.
Otherwise, if you do not remember the password, it will need to be reset:
- Select Can’t access your account? on the sign-in page and follow the verification steps.
- If self-service password reset is unavailable, contact your organization’s Microsoft 365 administrator or IT department to reset it.
I hope this answer is helpful and points you in the right direction. Please feel free to let me know if you have any additional questions.
