How To Manage Mailbox Permissions In Office 365

Assigning & Removing Mailbox Permissions for your users:

Mailbox permissions helps you to assign or remove permissions for the selected users on your user Mailboxes. Mailbox Permissions include Full Access permissions, Send As permissions and Send on Behalf permissions. Here is a brief explanation of what these permissions mean in Office 365.

Full Access permission allows the users to access to the mailbox. Users can open the mailbox and behave as the mailbox owner.
Send As permission allows the users to send email from another user’s mailbox. The email will appear to have been sent by the mailbox.
Send on Behalf permission allows the users to send email on behalf of the mailbox owner. The email will appear to have been sent on behalf of the mailbox owner.

The ‘Manage Mailbox Permissions’ feature available under ‘Microsoft 365 Manager’ module helps you to assign or remove mailbox permissions for your users in Office 365. When mailboxes are given access to multiple users, it is important that you manage such mailbox permissions with full audit trail of when permissions were granted and revoked. This helps you to keep your Office 365 secure by documenting and understanding who has access to other mailboxes. This also becomes important when you deprovision Office 365 users in your organization.
