How to Share a Folder in Outlook

If a colleague needs access to your inbox or a subfolder in your Microsoft Exchange email account, you can share the folder with them in Outlook. To share a subfolder, you'll need to grant your colleague permission to view your entire inbox. If you'd rather not share your inbox, you can create a "public" folder in your account and share that with specific users and groups. This wikiHow article will show you how you can share folders in the Outlook desktop app and on the web (OWA), plus how to delegate access to your email account so a colleague can send and receive messages on your behalf.

Sharing a Folder in the Outlook Web App

  1. Image titled Share a Folder in Outlook Step 1
    1
    Log in to Outlook on the web. Go to the Outlook URL provided by your company or campus to sign in to your email account. Or, if you've linked your Exchange account to your personal Outlook.com email address, you can sign in at https://www.outlook.com.
    • Sharing a folder is useful if you need someone to access your email while you're out of the office, or if the account is a group account that multiple people need to access.
    • If the person you're sharing the folder needs to send email on your behalf, you should delegate your account instead.[1]

    2
    Right-click your mail account name and click Permissions…. Before you can share a folder in your account, you'll need to first share your entire email folder.
    • If you don't want to give someone permission to see your entire email account, you can create a public folder and either move messages to that folder manually, or set up a rule to automatically sort certain messages into that folder.

    Select the person's name and choose a permission level. Make sure you've clicked the person's name at the top before selecting an option from the "Permission level" window.

    • You have to make sure you at least give the person permission to view your account so they will be able to access the folder you want to share. Choose the Reviewer permission level to grant view permissions only.[2] You'll still be able to give additional permissions, such as the ability to delete messages, for subfolders you want to share.
    • None gives the person no permission to the account. If you choose this option, you cannot share any folders with this person.

    6
    Check the box next to "Folder visible" and click OK. You'll see the checkbox in the bottom-right portion of the window. Now that you've granted this user permission to view your account, you can share the desired subfolder with them.
    • Sharing your mailbox only shares your inbox—not the folders inside of your inbox. You have first share your inbox and then share subfolders separately.
    • If you only want to share your inbox and not a specific folder inside of it, you're done here—skip to Step 10 to learn how the person you shared the folder with can access the folder.
  7. Image titled Share a Folder in Outlook Step 7
    7
    Right-click the sub-folder you want to share and click Permissions. This opens a Permissions window for the selected folder.
  8. Image titled Share a Folder in Outlook Step 8

    Add the user and choose their permissions. You'll do this exactly how you shared your mailbox—just add the user and choose a permission level.
    • The permissions don't need to be identical to those you granted to the entire inbox.
    • If you want the person to be able to create, read, modify, and delete items, as well as add their own subfolders, choose Publishing Editor. Editor permissions contains all of the same permissions as Publishing Editor, except the ability to create subfolders.
  9. Image titled Share a Folder in Outlook Step 9
    9
    Check the box next to "Folder visible" and click OK. The selected subfolder is now shared.
  10. Image titled Share a Folder in Outlook Step 10
    10

    • Right-click the account name in the folder list and select Add shared folder….[3]
    • Search for the name of the shared mailbox—this is the name of the person who shared the folder, not the name of a subfolder.
    • Select the mailbox and click Add.
    • The folder will then appear in the left column of Outlook for the web.

Article SummaryX

To share a folder with someone in Outlook, you'll first need to share your entire Outlook mailbox with read permissions, which grants that user permission to view your inbox and its containing folders. After your mailbox is shared, you can share specific subfolders with any permissions you want. Right-click your mailbox name and select Permissions or Folder Permissions, and then add the user with the desired permissions. Once granted, right-click the folder you want to share and grant that same user any permissions you want. The user can then add the shared folder to their own Outlook app.
