Sharing your mailbox via delegation
Note: Before proceeding, please review Best Practices for Sharing and Delegation – Office 365.
Delegation gives Office 365 users permission to access certain features of your mailbox, such as:
- Viewing and/or making appointments on your calendar.
- Looking at and updating tasks.
- Reading mail in your inbox and sending mail on your behalf.
If you have access to another's account and act on their behalf, you are known as a delegate. If the other person does not need to be a delegate, you can use conventional sharing (see Sharing your Calendar and Sharing mailbox folders) to grant them a more limited form of access.
