Cloud Drive Mapper v2.18 (Moderate Release)

“What’s in this release?”
Following the major release of Cloud Drive Mapper 2.15, we have made some further enhancements to the connection with Microsoft 365 in order to improve resilience, we have also fixed a few bugs.

“Do we need to update?”

  • The only customers who we definitely recommend to update are those who’ve actively seen issues with the Teams converged drive, if you aren’t experiencing any issues then you need not update.

  2. Upgraded code certificate to HSM certificate
  3. Added resilience to getting MS Teams information from the MS Graph API
  4. Added resilience to evaluating if user has access for browse directory on their OneDrive
  5. Updated WebView2 to latest binaries
