In Outlook, people can permit someone else to access their mailbox (e.g., inbox and calendar). This feature is called Delegate Access. Outlook allows another person, known as a delegate, to create and respond to meeting requests as well as sending and responding to e-mail messages on another's behalf.  A delegate can be assigned a range of permissions, including the ability to read, create, or have full control over items in the delegator's Exchange mailbox.

The person granting permission, the delegator, determines the level of access given to the delegate. Among other options, a delegate can be permitted to perform the following tasks:

• Read items in folders
• Read, create, modify, and delete items
• Send and respond to e-mail messages on the delegator's behalf
• Organize meetings and respond to meeting requests and task requests on the delegator's behalf

Delegate Access is most commonly used between a manager and assistant, where the assistant (delegate) is responsible for processing the manager's incoming meeting requests or email messages and coordinating the manager's schedule. Delegate Access can be used between peers as well (e.g., to coordinate schedules).

Microsoft provides instructions to manage delegate access:

• About delegates: Allow someone to manage your mail and calendar
• Allow messages to be sent on your behalf when sharing a folder or mailbox
• Share and access another person's mailbox or folder in Outlook
• Share and access a calendar with edit or delegate permissions in Outlook
• Become a delegate or stop being a delegate in Outlook for Mac
• Add and manage delegates in Outlook for Mac
• Options for sharing and delegating folders in Outlook for Mac

Note: If granting mailbox folder access, set permissions appropriately on the root mailbox folder (uniqname@med.umich.edu), in addition to the folder(s) you intend to share (e.g., Inbox).
