Set Boundaries for an Administrator Who Manages Mailboxes

Define the job before assigning access

Start by writing down the operational task that requires mailbox administration. Examples might include maintaining organisational mailboxes or carrying out an approved account change. A vague reason such as “help with email” is not enough to determine what access someone needs. Specify the responsibility, who authorised it and which mailboxes or administrative duties it covers.

Separate mailbox administration from ordinary mail use. A person who needs to read and send their own email may not need authority to manage other mailboxes. Similarly, a colleague who occasionally helps with a technical issue should not automatically receive ongoing administrative access. Choose the narrowest role or permission available that allows the assigned task, subject to your internal policies and the controls provisioned for your workspace.

Make authorisation explicit

Have an appropriate owner or manager approve the access before it is granted. Record the person, the work need, the scope of responsibility and any relevant end point, such as completion of a temporary assignment. Keep the record where your organisation expects access decisions to be documented; do not rely on an informal assumption that someone “probably” needs the privilege.

Tell the administrator what they are authorised to do and where to raise a request that falls outside that scope. This helps prevent a practical workaround from quietly becoming a broader standing privilege. Follow internal procedures for approvals, handling sensitive information and reporting concerns. A product control does not replace those organisational rules.

Check the actual role and available controls

Before assigning or changing access, confirm the person’s current role and the controls available to that role. BITTU Mail workspace administration includes domain and mailbox administration, but the specific controls available depend on role, plan and provisioning state. Do not assume that a setting is enabled for every account or that a particular administrator can perform every action.

Where the authorised workspace or domain administrator has access to the relevant administration area, they can use the controls available there for their own organisation. If an expected option is unavailable, check the person’s assigned role and ask the appropriate workspace owner or administrator to clarify provisioning. Do not work around missing authority by sharing another person’s login. Admin permissions and quotas are enforced server-side.

Review access when responsibilities change

Treat access review as a recurring part of administration, not just a setup task. Recheck who has administrative privileges when staff change responsibilities, an assignment ends, or the organisation updates its policies. Periodically compare the access record with the people who currently perform the work. Ask whether each person still has a clear operational need and whether their scope remains appropriate.

If a person no longer needs access, have an authorised administrator remove or adjust it using the controls available to their role. Record that the review took place and note any follow-up that could not be completed. The review does not establish that every possible permission has been removed; confirm the resulting role or access state using the administrative information available to an authorised person.

Use a simple review example

Suppose a team member was authorised to maintain organisational mailboxes during a defined project, and the project has now ended. The review should not assume that the original reason still applies. The responsible owner can check the documented approval, confirm with the team whether the task continues, and ask an authorised workspace administrator to adjust access if it is no longer needed.

Review note
Person: [team member]
Approved task: [specific mailbox administration duty]
Authorised by: [role or approver]
Current need confirmed by: [responsible owner]
Follow-up: [retain, adjust or remove access]
Confirmation: [authorised administrator checks the resulting role]

Confirm the change and close the loop

After an access change, ask the authorised administrator to check the resulting role or access state in the controls available to them. Compare it with the approval and the task the person is meant to perform. If the person still needs some administration, confirm that the remaining access matches that need rather than treating a partial reduction as complete without checking.

Keep a concise record of the decision and confirmation according to internal policy. If the available controls or resulting state are unclear, pause and consult the responsible workspace owner or support channel rather than guessing. A clear approval, a suitably limited role and a recorded review make it easier for the organisation to explain why administrative access exists—and when it should change.

• Identify the specific operational need and approver.
• Check that the assigned role is appropriate for that need.
• Revisit access after role changes and during periodic reviews.
• Have an authorised person confirm the resulting access state.
