Folder sharing lets other people access one or more folders. However, it does not include permissions for them to act on your behalf. For example, a person who can access your folders can’t reply to email messages or respond to meeting requests for you. If you require another person to act on your behalf, use the "How to Manage Delegates (in Outlook/OWA)" guide.

Folder Permissions:

  1. Login to OWA (
  2. Right click on your name in the Mailbox list on the left side of the window.
  3. Select Permissions…

  4. Click the +button to add a new person

  6. Select the desired permission level (Reviewer is recommended) - Folder visible must be a selected option.
  7. Click OK

  8. Repeat steps 2-7 for the folder(s) you wish to share.
