Hi All,

I am using an Exchange Hybrid environment where users are created on-premises and then migrated to Exchange Online. I have a user, for example user1(at)contoso.com. In Outlook, user1 has a folder named Projects, which contains multiple subfolders, such as:

Projects

├─ Project A

├─ Project B

│ └─ Project B1

└─ Project C

User1 wants to provide access to user2(at)contoo.com and user3(at)contoso.com on the Projects folder. The requirement is that user2 and user3 should:

Be able to access all existing subfolders under Projects

Be able to create new folders under the Projects folder

Have access to any new subfolders created in the future

Please guide me to configure this?

    To provide access to the Projects folder and its subfolders for user2 and user3 in an Exchange Hybrid environment, you can use the Add-MailboxFolderPermission cmdlet in PowerShell. Here’s how you can do it:

    1. Connect to Exchange Online PowerShell: First, ensure you are connected to Exchange Online PowerShell. You can do this by running the following command: 
         Connect-ExchangeOnline -UserPrincipalName ******@contoso.com
    2. Grant Folder Permissions: Use the Add-MailboxFolderPermission cmdlet to grant user2 and user3 the required permissions on the Projects folder. You need to specify the access rights you want to assign. For example, to give them Editor access, which allows them to create new folders and manage existing ones, you can run: 
         Add-MailboxFolderPermission -Identity "******@contoso.com:Projects" -User ******@contoso.com -AccessRights Editor
   Add-MailboxFolderPermission -Identity "******@contoso.com:Projects" -User ******@contoso.com -AccessRights Editor
    3. Inheritance of Permissions: By granting permissions at the Projects folder level, user2 and user3 will automatically have access to all existing subfolders and any new subfolders created in the future under the Projects folder.

    Make sure to replace ******@contoso.com, ******@contoso.com, and ******@contoso.com with the actual email addresses of the users involved.

    After executing these commands, user2 and user3 should have the required access to the Projects folder and its subfolders.
