Zee Drive for Office 365

Map OneDrive for Business & SharePoint to Network Drives

Are you replacing your file server with Office 365 and OneDrive for Business but don't want to lose the familiarity and ease of working with your files through mapped drives and file shares? Then take a look at Zee Drive to find out how it makes Office 365 work as your new file server.

Zee Drive maps OneDrive for Business, team sites, SharePoint Online document libraries, shared with me files and Office 365 group files to network drives giving you access to your files through the familiar interface of Windows File Explorer in a similar way as if you were accessing them from a local file server.

Mapped drives are persistent and available when users sign in to their PCs. The mapped drive configuration is managed centrally by Zee Drive so you can easily deploy changes to drive mappings to all users in your organisation.

Zee Drive can minimise disruption to end users and greatly reduce the need for training when transitioning to Office 365 because users work with their files in a familiar way.

If you are considering deploying Zee Drive to your customers then find out about our Zee Drive partner subscriptions. With a partner subscription you can white label parts of Zee Drive and administer all your customer subscriptions from a single interface. With a partner subscription you can provide a "managed cloud file server" solution for your customers.

How Office Document Locking Works in Zee Drive

When opening an Office document on a local file server through a mapped network drive, Office will report that the document is already locked for editing if another user has already opened the same document. The user has the option to open the file readonly or wait for the file to be available for editing.

This familiar user experience for locked Office documents is supported with Zee Drive mapped network drives. On opening a document in Office, a server side lock is taken out on the document preventing other users from opening the document for editing in Office.

  • When opening an Office document from a Zee Drive mapped network drive, if the document is already locked, Office informs the user and offers some options.
  • Zee Drive Screenshot

Zee Drive attempts to maintain the lock on the document for the duration the document is opened from Zee Drive. On closing the document, the lock is released, allowing another user to open the document for editing.

The specific Office applications supported are Excel, Word, and PowerPoint and the document types .doc, .docx, .xls, .xlsx, .xlsm, .ppt, and .pptx.

Reporting And Recovery Of Failed File Uploads

Zee Drive provides capabilities for end users to recover file uploads that have failed, for administrators to identify computers with recovered files, and a special recovery mode to save recovered files from computers where Zee Drive has been deactivated.

When a file fails to upload through a Zee Drive mapped drive Zee Drive recovers the file and notifies the user. The user can then save the recovered file to a location on their computer. Zee Drive limits how many files can be held in recovery; if the limits are breached Zee Drive will write-protect the drives temporarily until the user has saved the recovered files. Users have up to 4 weeks to save the recovered files before Zee Drive purges them.

  • Zee Drive notifies the user when files have failed to upload.
  • Zee Drive Screenshot
  • Users can select the recovered files and save them from Zee Drive to their computer.
  • Zee Drive Screenshot

Zee Drive subscription administrators can view reports tracking which computers have unsaved files. Even if a computer has since been deactivated administrators can still discover which computers had unsaved files at the time of deactivation.

  • Administrators can track computers with unsaved files.
  • Zee Drive Screenshot

If Zee Drive has been deactivated on a computer the recovered files can still be saved by running Zee Drive in recovery mode. To do this enter the following command from a command prompt in the same folder where the Zee Drive executable resides:

zeedrive.exe Command=Recover

Zee Drive will startup in recovery mode and list any unsaved files from subscriptions that have been deactivated by the user that is signed in to Windows.

Files that failed to save directly from Office (Word, PowerPoint, Excel) will not be recovered as Office prompts the user directly to save the file to another location.

Zee Drive in Shared Computer Environments

Zee Drive supports shared computers; a shared computer is where many people may use the same computer but only one person will be on the computer at a time. Examples include hot desk computers at the office, lab computers or school library computers.

When activating as a shared computer, a shared computer licence will be assigned to the computer. Zee Drive will then startup for all users signing on to the computer. If the user signing on to the shared computer has a Zee Drive user licence assigned to them (either a personal computer user licence or shared computer user licence) then Zee Drive will map their drives.

If the shared computer is joined to an Active Directory domain then Zee Drive will automatically resolve the user's Office 365 username when they sign in to the computer. If the shared computer is not domain joined then users will be prompted to enter their Office 365 username the first time they sign in.

A computer can be activated as a shared computer manually using the Zee Drive wizard, or automatically through the Zee Drive command line. The command line is useful when you have many computers to install and activate Zee Drive on. Zee Drive provides a log you can access centrally to track the status of command line activation attempts.

  • To activate a shared computer manually, run Zee Drive on the shared computer and enter your administrator username and activation code. Click the blue "shared computer" link to start.
  • Zee Drive Screenshot
  • Enter a unique name to identify the shared computer on your subscription.
  • Zee Drive Screenshot

Follow the remaining steps to activate the computer as a shared computer. You may need to restart the computer after activation

Zee Drive provides an alternative method of activation using the command line. This is useful when you have many computers to activate and want to do that automatically.

  • To activate shared computers using the Zee Drive command line choose the 'Activate Zee Drive on shared computers' option from the menu.
  • Zee Drive Screenshot

Zee Drive will then walk you through the process of enabling activation with the command line. Command line activation first needs to be enabled. Once enabled you can click the how to use the command line link to view the command line and copy it to the clipboard.

  • Manage shared computer activation using the command line.
  • Zee Drive Screenshot

A log of all attempted activations by the command line can be accessed directly from Zee Drive by clicking the View Activation Log button from the above screen. This will help you to track the results of command line activation and troubleshoot those attempts that failed.

  • The activation log showing attempted activations from the command line.
  • Zee Drive Screenshot
  • To manage the shared computers you have activated choose the "Manage your shared computers" option from the menu on the Zee Drive status screen.
  • Zee Drive Screenshot
  • From the management screen you can deactivate your shared computers or set the Active Directory username lookup attribute.
  • Zee Drive Screenshot

When a user next signs in to the shared computer Zee Drive will automatically start up for the user. The Office 365 username of the user signing in to the shared computer is looked up from Active Directory. The Active Directory property from which the Office 365 username is looked up defaults to UserPrincipalName. This can be changed to another property such as Mail.

If the shared computer is not domain joined then the user will be prompted to enter their Office 365 username the first time they sign in to the computer. Zee Drive will save their username so the next time they sign in Zee Drive will start up without prompting the user again.

  • Zee Drive will prompt the user for their Office 365 username if the shared computer is not domain joined.
  • Zee Drive Screenshot

If federated identity (ADFS) is used with Office 365 then the user will be signed in to Office 365 automatically by Zee Drive. If federation is not used then the user will be prompted for their Office 365 credentials. The credentials are persisted to the Windows Credential Manager as enterprise credentials. When the user signs out of the computer the credentials will then roam with them when they sign in to another domain joined computer.

Zee Drive can be upgraded to a newer version by using the following command line on the shared computer (running as local administrator):

zeedrive.exe Command=UpdateShared

To upgrade a shared computer manually run Zee Drive on the shared computer and enter your administration username and activation code then click the blue "shared computer" link. You can now choose to deactivate or upgrade Zee Drive.

  • If a shared computer is already activated you can manually upgrade it or deactivate it.
  • Zee Drive Screenshot

View File And Folder Changes On-Demand

If a file or folder change is not yet showing in a user's mapped drive the user can download the latest changes on-demand. Click the F5 button (refresh button) on your keyboard whilst Windows File Explorer has the focus and Zee Drive will update the folder in real-time to show the latest changes.

  • In the example below a recently added document, "Myles Team Presentation.pptx", is not yet showing in Windows File Explorer so just click the F5 button on your keyboard.
  • Zee Drive Screenshot
  • After clicking F5 the new document will appear.
  • Zee Drive Screenshot

View Version History From File Explorer Context Menu

The version history of files in your Zee Drive mapped drives can be viewed from the Windows File Explorer context menu. Zee Drive will show a list of the latest versions including the version number, modification date, file size and whom made the change.

  • Select a file in File Explorer, right click the mouse button to show the context menu then choose the version history command.
  • Zee Drive Screenshot
  • Zee Drive will then display the recent version history of the selected file.
  • Zee Drive Screenshot

Zee Drive subscription administrators can choose whether or not to show the version history command on the File Explorer context menu.

  • Choose "Manage the File Explorer context menu" command from the menu button.
  • Zee Drive Screenshot
  • Then choose whether to enable or disable the version history command.
  • Zee Drive Screenshot

Note that the version history context menu command will show only on 64 bit versions of Windows.

Map A Network Drive To Shared With Me Files

When a user shares a file or folder with you from their OneDrive for Business the shared item will appear in your Shared With Me area in Office 365. Zee Drive can show these files and folders directly in a mapped network drive.

Zee Drive groups the shared items in folders named after the user that shared them. For example, if user "Myles Jeffery" shares a file with you then the shared file will appear in the folder "Myles Jeffery" in the mapped network drive.

  • Files and folders shared with you are grouped under folders bearing the name of the person that shared the item.
  • Zee Drive Screenshot
