It’s easy to create a mailbox – you can use either Microsoft 365 admin center or Exchange Online PowerShell. But, managing a mailbox is not an easy job because you have to worry about things like

  • Mailbox usage,
  • Mailbox permissions,
  • Mailbox size and quotas,
  • Mailbox forwarding,
  • Mailbox policies,
  • Mailbox settings,
  • Mailbox holds, etc

Most administrators might be fed up when they want to get mailbox details through the Exchange admin center because of its ever-changing UIs and inadequate information. Few of them will choose PowerShell. Without having basic PowerShell knowledge, it’s hard to create your own script or to customize an existing script to meet your requirement.

Even though you put a lot of effort into PowerShell to get the required report, that is nothing compared to what AdminDroid provides you. Yes, AdminDroid Office 365 reporting tool is specifically designed to solve Office 365 administrators’ reporting and auditing needs. It gives data in a readable and understandable format irrespective of how APIs or PowerShell throws the result.

AdminDroid provides dedicated reports on each category such as mailbox usage, permissions, etc., to know more about the mailboxes. Besides, the tool provides reports on mailbox security like email forwarding to an external address, non-owner mailbox access, mailbox delegation, etc.

Never Run out of Space, Keep an Eye on Mailbox Usage Size:

The mailbox size is predetermined based on the mailbox type and subscription. When a mailbox reaches its limit, the user can’t send and receive emails. By knowing the mailbox size and quota status, the admin can increase the mailbox size.

To know about mailbox usage size, AdminDroid provides reports on

  • Mailbox size report – Lists all the mailboxes with their size, storage-used percentage and quotas.
  • Mailbox over warning quota – Displays all the mailboxes that crossed their warning quota.

Control Automatic External Email Forwarding in Your Organization:

Automatic email forwarding can be useful, but it can also pose a security threat like leaking proprietary information, having a copy of the official email in personal email ids, etc. Hence, external forwarding indicates account compromises.

To find email forwarding configurations, AdminDroid provides dedicated reports based on the configuration methods and its nature.

Make Sure All the Mailbox Events Are Audited in Your Organization:

Mailbox auditing plays a major role in tracking user and administrator activities on the mailbox. In Office 365, mailbox auditing is enabled by default for each logon type (Admin, delegate, and owner). But default auditing does not track all the activities. Some activities like mailbox logins, copy, folder bind, move, record delete need to be enabled manually.

To improve the auditing capabilities, AdminDroid offers the following audit settings reports.

  • Audit enabled mailboxes – Lists audit enabled mailboxes along with their admin, delegate, and owner actions that are audited.
  • Audit disabled mailboxes – Shows mailboxes that are not audited.

  • Delegate audit enabled – ShowsAuditDelegate enabled mailboxes. Besides, the report gives mailbox actions that are being logged on.
  • Owner audit enabled – Shows mailbox with AuditOwner enabled and their owner actions being logged on.
