Sharing a folder in Outlook as the owner

To share a mailbox folder, you'll need to do the following in sequence:

1. Grant sharing permissions for your top-level mailbox
2. Grant sharing permissions to your mailbox folder(s)

Granting sharing permissions for your top-level mailbox

1. In the Home view of your mailbox, right click Folders and select Sharing and permissions.
   
   
    
2. Select + to grant a new individual access.
   
   
    
3. Enter the name or email address of the individual you'd like to grant access to. Then click Add.
   
   
    
4. Grant them Reviewer permissions to give them read-only permissions.

Granting sharing permissions for your mailbox folder(s)

The process to grant sharing permissions for your mailbox folders is the same as your mailbox:

1. Right click the folder you want to share and select Sharing and permissions.
   
    
2. Select + to grant a new individual access
    
3. Enter the name or email address of the individual you'd like to grant access to. Then click Add.
    
4. When granting permissions to this folder, you may want to give them the following permissions or higher:

• Reviewer: reviewers can read your messages
• Nonediting Author: nonediting authors can read your messages and drop messages into a folder
   

5. If the folder is a subfolder, repeat steps 1-4 for each folder the subfolder is nested in.

For a list of permissions levels and the corresponding actions a shared user can take, see Microsoft's article Options for sharing and delegating which is applicable to web and Outlook for Windows and Mac.

Opening a mailbox folder that's been shared with you

2. Search for and select the user who has shared folders with you, then click Add.
   
   
    
3. Their mailbox and shared folder will appear under your Folders list.
