| 2. | Open a Windows command window e.g. Start > Run > cmd | 
| 3. | Within the command window right-click and select Paste then press Enter e.g. |

| 5. | Within the command window right-click and select Paste then press Enter e.g. | 
 

 
The collections will have been recreated.
Note: If you get an error you may not have fully copied the text in bold, or you have an additional space at the start or end.
 
| 6. | To open the folder to retrieve the recreated collections copy the following text to the clipboard: %LocalAppData%\Oasys\Mail Manager | 
| 7. | Open Windows Explorer and paste the Paste path into the address bar e.g. | 
 

 
| 8. | The retrieved collections will be prefixed with “_”. Move the Collections back to they original folder and remove the underscore from the filename |
