"9hehw" ?11

Hello @Ahmed youssef,

For a 9hehw + "Access denied for the resource" error in New Outlook for Mac, I'd approach it as an account/authorization issue first, not an Outlook client issue. The error message itself indicates Microsoft is rejecting access to a required service resource.

As this question is tagged macOS / New Outlook for Mac, I'll provide troubleshooting steps for Mac. If you're using a different operating system, please let me know so I can tailor the troubleshooting steps accordingly.

Please try the following steps first:

• Quit Outlook completely.
• Open Keychain Access (Applications > Utilities > Keychain Access).

For your reference: What is Keychain Access on Mac? - Apple Support (VN) (Note: This link is shared by community members for your convenience.

• Search for entries related to:
  • Outlook
  • Exchange
  • Microsoft Office
  • Microsoft 365
• Delete the related Outlook/Exchange credentials.
• Restart your Mac.
• Open Outlook and add/sign in to your account again.
• Make sure Outlook is updated to the latest version before testing.

If the issue persists, please let me know:

• Can you successfully sign in to https://outlook.office.com or https://portal.office.com using the same account?
• Does this affects only one user or multiple users in your organization?
• Is the affected account an end-user account, or does it have administrative privileges (Global Admin, Exchange Admin, etc.)?

This information will help determine whether the issue is related to cached credentials on the Mac, an account permission or configuration issue, or a server-side problem affecting the sign-in process.

Looking forward to your reply so we can get this sorted out for you together.
