The Recover Deleted Items functionality in Office Outlook 2007/2010 for shared mailbox

In Office Outlook 2007/2010, you do not have to make any changes to the registry to enable the Recover Deleted Items menu for any folders in your mailbox. The Recover Deleted Items menu is available by default in Office Outlook 2007/2010. But if you have added secondary mailbox in your outlook 2007/2010 then you will not see recover deleted items for shared mailbox folders.

To Enable recover delete item for shared mailbox you need to enable registry setting manually (Remember old days 🙂 ).

To enable recover deleted items in shared mailbox, I am going to create one shared mailbox “_ABC Finance HelpDesk”. Test1 mailbox is a user mailbox and it has full mailbox access to shared mailbox “_ABC Finance HelpDesk”.

If you see below, Recover deleted items option is not visible for shared mailbox, So now I am going to add registry value manually.

1. Start Registry Editor.
2. Locate and then click the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Options
3. On the Edit menu, click Add Value, and then add the following registry value:
Value name: DumpsterAlwaysOn
Data type: DWORD
Value data: 1
4. Close Registry Editor.

Once registry value is added then exit outlook and launch it again.

Once I have added registry value in user “Test1” machine, Now I am able to see “Recover Deleted Items”. And now you can see old deleted items on base of your server retention policy.
