Known Issues & Limitations

Known Issues

Windows Desktop Client


  1. Zip files cause "double encryption" 
    When extracting a zip archive containing encrypted files to a location governed by an encryption rule, the extracted files will be encrypted a second time in accordance with the encryption rule. It is recommended that users avoid extracting files known to contain encrypted files into a location where an encryption rule is in place. Files with double-encryption can be decrypted by first moving them to a location where there are no encryption rules in place, and manually decrypting them. They can then be moved back to the intended location where they will be automatically encrypted again in accordance per the encryption rule.

MS Teams

  1. If a user changes the default file open preference setting away from "Desktop app", it will remain that way until Teams is relaunched.
    The SmartEncrypt Desktop Client forces the default method of opening files to be set to "Desktop app" whenever Teams is launched.  This means that encrypted  Word, Excel, and PowerPoint files will open seamlessly in their associated Office desktop app for viewing and/or editing without user intervention.  If a user changes their default file open preference to something other thatn "Desktop app", users will encounter errors trying to access these files as the Teams app is unable to access encrypted content. Users can change the default back to "Desktop app" manually, or it will be restored once the Teams app is relaunched.

SharePoint Online "Virtual Client"

  1. Only a limited number of individual files can be decrypted at once
    When decrypting multiple individual files in a SharePoint location that is no longer governed by an encryption rule, you may encounter an error "Too many files selected. Please reduce the number of files selected and try again." This is due to a limitation in SharePoint when parsing query strings.  

  2. Nested rules are not supported in SharePoint Online
    When creating encryption rules with the Windows Desktop Client, it is possible to create nested rules using 2 different encryption keys. This is currently not possible when creating encryption rules within SharePoint Online.  It may be supported at a later date and we welcome feedback regarding this feature.

  3. Encryption rules with exclusions are not supported in SharePoint Online
    When creating encryption rules within the Management Console, its is possible to designate folders within a designated location to be excluded from having the encryption rule applied.  This festure is currently not available when creating encryption rules within SharePoint Online but may be supported at a later date pending demand. We welcome feedback regarding this feature.


Windows Desktop Client


  1. SmartEncrypt overlay Icons are not visible in OneDrive
    Problem: SmartEncrypt overlay icons do not appear on encrypted files or folders when browsing files in OneDrive in the icon, content or list views. 
    Workaround: Browse OneDrive using the details view - an additional “SmartEncrypt” status column has been implemented in this view to display the SmartEncrypt icon.  When encrypted files/folders are moved to another location outside OneDrive, the SmartEncrypt overlay icon will appear automatically, regardless of folder viewing mode. 
    Note: The SmartEncrypt icon is not visible for encrypted Online-only files (blue cloud status icon), files must be available on the local device to view the encryption status.

  2. Moving or copying Online-only files in OneDrive to a rule-based location does not encrypt the file
    When performing drag and drop or copy/cut and paste operations on a file with Online-only availability from one location in One to another location governed by an encryption rule, the file does `not adopt the encryption rule. This is because the file remains in the cloud and there is no interaction with the SmartEncrypt software to trigger the encryption process
    Workaround: Ensure files are first made available on the local device before attempting to move to enable the encryption process to be triggered.

  3. Some office files in OneDrive are decrypted when opened, but not re-encrypted when closed
    Problem: SmartEncrypt is not compatible with OfficeSync for OneDrive and causes encrypted files in OneDrive that are not governed by encryption rules to decrypt on open, and remain decrypted when closed, even if the file has not been modified.
    Workaround: Disable the Use Office applications to sync Office files that I open checkbox. Note that this limitation is applicable to individually encrypted files only, files governed by encryption rules are not affected. Learn more about Office sync

MS Teams

  1. Encrypted PDF files cannot be viewed in MS Teams
    Problem: When attempting to view an encrypted PDF file in MS Teams, users encounter a file unreadable error, even if the default file open preference is set to "Desktop app".
    Workaround: Choose the "Open in browser" option when viewing encrypted PDF files, this will force the PDF to be opened in the device's default PDF reader application (if installed).

Citrix ShareFile

  1. Citrix Files for Windows decrypts files added to the ShareFile drive
    There are 2 desktop clients available for use with Citrix FileShare - Citrix Files and Citrix Sync. SmartEncrypt is not compatible with Citrix Files.  This is due to the virtual mounted drive that is created by the Citrix Files client. Encryption Rules have no effect and encrypted files added to the Citrix shared drive will be decrypted if the user has the correct encryption key.
    Workaround: Consider using the Citrix Sync client, which creates a folder instead of a mapped drive. SmartEncrypt file encryption behaves as expected with the Citrix Sync client.

SharePoint Online "Virtual Client"

  1. Renaming the top-level folder where an encryption rule is in place causes the encryption rule to break
    Problem: If you create an encryption rule in SharePoint and the folder on which you created the rule is renamed, the rule will be broken.  When the folder is renamed, the existing SharePoint encryption rule becomes invalid as the location no longer exists. Files within the location will remain encrypted, but new files added to the location will not be automatically encrypted as the rule will no longer apply.  This is due to the SharePoint app having no direct communication with the Management Console, other than when creating and deleting rules via the SharePoint interface, so the Management Console is not aware of changes to folder names.
    Workaround: Restore the folder name and the rule will be reinstated. Alternatively, create a new rule using the same encryption key for the renamed folder (the previous rule can then be deleted).

  2. Renaming an encryption key in the Management Console is not reflected in SharePoint
    Problem: When an encryption key used to encrypt a location in SharePoint Online and that encryption key is renamed, files encrypted with the key do not show the updated key name until they are modified. This can result in files appearing to be encrypted with a different encryption key, when it is in fact the same key.
    Workaround: There is currently no workaround available other than to modify files either by editing or uploading new versions, at which point file will adopt the updated encryption key name.
