Allow managed account email addresses to be changed to a domain not verified at the organization

Issue Summary

As an org administrator, when a domain is verified, all the accounts belonging to it will become managed by the organization, which will allow the administrators to edit the profile details of these users, like the email address.

During the recent changes, admins can no longer update an email of an account to a domain not managed by the organization. When attempting to change it, the following will be displayed:

You are unable to change the email address of a managed account to another domain that is not managed by your organization.

 This information is also included in the article to make changes to managed accounts.

Suggestion

For some organizations, this can be useful for scenarios like the following:

• For educational institutions, when a member is no longer part of the institution, they could have their email changed to personal ones if they have access to personal content, like Trello boards or content created in the Atlassian products used by the organization.
• When someone mistakenly create personal content in the work account, they could change the user's email address to a personal one and create a new dedicated account to allow the user to still have access to the content.

This is a suggestion to allow admins to change the email to domains not managed by the organization.
