Access another person's mailbox Office 365

As long as you have been granted permission to access another person's mailbox, you can access it.

Here are some scenarios to consider:

• Managers need assistants to monitor emails on their behalf. An assistant can view a manager's mailbox.

• Managers need assistants to monitor specific folders in their mailboxes. As a result, an assistant who has been granted permission to view a specific folder in a manager's mailbox can only see the contents of that folder.

Microsoft 365 email accounts and Microsoft Exchange-based email accounts are the only ones that can use this feature.

It is assumed that you have already been granted permission to access the email account of the other person in this article.
