Error message "Access denied for the resource." Tag 9hehw

Hi Chris Casey,

I understand that Outlook on your new Mac displays “Access denied for the resource” with tag 9hehw when you try to add your personal account.

Please note that this is a user-to-user forum, so contributors cannot examine the account or the sign-in request directly. To determine the correct setup path, could you confirm the following?

1. Are you trying to add an email mailbox to Outlook, or sign in to activate/connect your Microsoft 365 Personal subscription?
2. Does the address end in @outlook.com, @hotmail.com, @live.com, or @msn.com, or is it from another provider such as Gmail? Please share only the part after@.
3. What Outlook version appears under Outlook > About Outlook, and was Outlook installed from the Mac App Store or directly from Microsoft?
4. Can you sign in to the same account successfully at Microsoft account?

These details are important because an Outlook.com mailbox and a third-party address associated with a Microsoft 365 subscription use different setup paths in Outlook for Mac.

Once these details are confirmed, the appropriate steps can be provided without repeating unnecessary troubleshooting.
