"Add mailbox" button not taking users to the new revamped screen

[Imran92]

The Add mailbox button is not taking users to the revamped screen, instead takes to the legacy one

[github-actions]

OpenAI suggested the following labels for this issue:

• [Feature Group] Emails & Domains: The issue relates to an email action ('Add mailbox') that is not functioning as intended.
• [Feature] Email Integration: This feature pertains specifically to the email service which includes adding mailboxes, and since the button is supposed to redirect to an email management screen, this label is relevant.
• [Feature] Authentication: The issue may affect user authentication flows if the 'Add mailbox' functionality is linked to user credentials or access to email features.
