accessing sub folder of a shared mailbox 'directly'

[CB1]

In the classic desktop version of Outlook for Windows (version 2302) or Outlook web access, if someone has been granted access by a colleague to a particular folder on a shared or user mailbox, e.g. inbox or inbox\subfolder ONLY, but has not been granted full mailbox access or access to the 'top of the information store' folder, is there anyway to still access/map to the inbox folder directly (or whichever folder their colleague has granted them access too)? And if so how do you add the specific folder manually so you can make use of the permissions granted? 

I know there are many scenarios whereby someone may only wish to grant a colleague access to a specific folder of their mailbox, and not the full mailbox, but I'm not sure how they map directly if they havent been granted full mailbox access.

There's no direct way to access a specific folder in a shared mailbox unless you have full access or access to the "top of the information store" folder.

Workarounds include:

1. Request full mailbox access.
2. Use folder permissions for the subfolder.
3. Delegate access for specific actions.
4. Share the calendar if it contains calendar items.
5. Manually add the folder in OWA (may not always work).
It's best to request the appropriate permission level from the mailbox owner.

Have you got any further info or links to articles on options 2 and 5 please? So I can try those manual mapping methods before we request a tweak to permissions? e.g. do you manually add the folder in OWA and specify the sub folder, e.g. mailbox @ company . com \inbox

N/B these are sub folders of inbox or the inbox folder itself, and not calendars. For info access was granted by the owner of the mailboxes via 'folder permissions' and not via an admin in Exchange itself.

Hi @CB1,

For Outlook on Windows:

1. Begin by sharing the primary folder first, and then set sharing permissions for the desired subfolder.
2. Open a shared mailbox by selecting a folder within the Shared Mailbox on the Folder Panel to the left.
   
   

For Outlook Web Access:

1. The shared mailbox and its folders are visible in the left navigation pane each time you open Outlook on the web.
2. Expand or collapse shared mailbox folders, similar to your primary mailbox.
