In Outlook versions prior to Outlook 2007, deleted item recovery is possible only from the deleted items folder. This means if you permently delete an email from your inbox, you wont be able to recover it - which is stupid! You will notice when you go to "Recover Deleted Items" it will be greyed out.
To enable it so a user can restore deleted items regardless which outlook folder they delete the email from perform the following steps:
1. Run regedit on client workstation and locate following hive
3. Add a DWORD and name it DumpsterAlwaysOn
4. Give the newly created DWORD a value of 1
5. If Outlook is running, close it and restart it.
6. Set Outlook Client to open user’s mailbox
7. Highlight inbox
8. Select recover deleted items from the tools menu
9. Select the messages that need to be recovered and click on the recover button.
What happens if you want to make this option available to all users in your organisation?
You can create an ADM template and deploy this registry change to all your workstations. To do this flow these steps:
