Cloud Drive Mapper (v2.8 and above) now supports the ability for your users to set-up their own drives to OneDrive, SharePoint Online and Microsoft Teams. Customers normally centrally administer this process but we have encountered a number of organisations who would prefer to give their users autonomy to handle this themselves. 

As such, this feature is off by default and has to be activated by a registry key.


How to enable 'Manage My Drives'

  1. Ensure you're using CDM v.2.3.3 or above (download latest version)
  2. Go through the 'advanced mode' AAD admin permissions process (see knowledge-base article)
  3. Create/deploy a registry key string EnableAdvanceMode value = true (this is not needed on v2.9 and above)
    - recommended to Computer\HKEY_CURRENT_USER\Software\IAM Cloud\CloudDriveMapper
    - else to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\IAM Cloud\CloudDriveMapper
    REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "EnableAdvanceMode" /t "REG_SZ" /d "true" /f
  4. Create/deploy a registry key string CustomDriveSettings
    - recommended to Computer\HKEY_CURRENT_USER\Software\IAM Cloud\CloudDriveMapper
    - else to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\IAM Cloud\CloudDriveMapper

CustomDriveSettings is a regular bitmask which can modify multiple settings at the same time, to calculate the precise settings you want, add the numbers of the feature below together.    


Version 2.8.x.x and earlier

  • 0 or does not exist in registry means it is off     
  • 1 = AllowConverged     
  • 2 = AllowManual     
  • 4 = AllowSelections     
  • 8 = AllowOneDrive    
  • 16 = AllowManualWithoutDocLib


If you wish to enable all functionality use the value 31


REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "CustomDriveSettings" /t "REG_SZ" /d "31" /f


Version 2.9.x.x and later

  • 0 or does not exist in registry means it is off     
  • 1 = AllowConverged     
  • 2 = AllowManual     
  • 4 = AllowSelections     
  • 8 = AllowOneDrive    
  • 16 = AllowManualWithoutDocLib
  • 32 = AllowShortcuts


If you wish to enable all functionality use the value 63


REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "CustomDriveSettings" /t "REG_SZ" /d "63" /f


How your users create their own drives

  1. Users should navigate to the Cloud Drive Mapper client in the System Tray and right click
  2. The users will now see an option 'Manage my drives', click this
  3. A pop-up window will appear where users can select:
    • A dropdown list with available drive letters
    • A dropdown list with all of their available SPO & Teams Sites (that they have permission to access)
    • A second dropdown with the available document libraries (that they have permission to access)
    • A field where they can enter their drive name
  4. Users can add as many drives as they want (within the letters available), and then click 'Apply'. This popup window will disappear, and CDM will begin mapping the new drives
  5. Users can be blocked from using certain drives letters with the reg key ManageDriveBlockList. For example to prevent users from using the letter A, set ManageDriveBlockList value = A. These can be comma delimited too to block multiple letters
    REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "ManagedDriveBlockList" /t "REG_SZ" /d "A" /f
  6. The config data is stored in each user's OneDrive account, which means it will persist across different sessions and machines. To disable this you can set the reg key SaveConfigToOD value = false (see knowledge-base article
  7. The converge drives can be further customised with the MasterSettings reg key (see knowledge-base article)


REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "ManagedDriveBlockList" /t "REG_SZ" /d "A" /f




How to isolate which types of locations that user can map to

  1. This is controlled by the reg key ManageDriveTemplates
  2. By default CDM will allow all types of mapping, however this can be isolated where applicable by using guids below. SharePoint sites will show both classic and groups, SharePoint Groups will show only modern sites which are backed by a unifed group:
    • 0fae2f3e-f12d-49ef-82d8-d27d9abefbc5 - SharePoint Sites
    • 0d610af7-804e-4313-846c-5be310d5e3dc - Teams
    • e0932e84-800b-4785-b5b5-b88a51eb34ea - SharePoint Groups
  3. This key can be used in conjunction with the MasterSettings option too. For example, you can have ManageDriveTemplates set to SharePoint Sites only, and MasterSettings set to OnlyShowSiteWithGroups in order to limit the locations down
  4. Should you wish to have two different sources from the table, simply comma delimitate like:
0fae2f3e-f12d-49ef-82d8-d27d9abefbc5,0d610af7-804e-4313-846c-5be310d5e3dc,e0932e84-800b-4785-b5b5-b88a51eb34ea


REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "ManageDriveTemplates" /t  "REG_SZ" /d "0fae2f3e-f12d-49ef-82d8-d27d9abefbc5" /f
REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "ManageDriveTemplates" /t  "REG_SZ" /d "0d610af7-804e-4313-846c-5be310d5e3dc" /f
REG ADD "HKCU\Software\IAM Cloud\CloudDriveMapper" /v "ManageDriveTemplates" /t  "REG_SZ" /d "e0932e84-800b-4785-b5b5-b88a51eb34ea" /f
