[Update] 9/8/2019

Users with SafeGuard Enterprise client version 8.00.5 may encounter issues after installing the Microsoft July cumulative updates for Windows 10 version 1903 (19H1), KB4505903 and version 1809 (RS5), KB4505658. If you use any of the file encryption modules of SafeGuard Enterprise 8.00.5, Sophos recommends that you do not install the above updates or remove these from affected systems.

Computers running SafeGuard Enterprise 8.10 or later, running Windows 10 versions earlier than version 1809 (RS5), or that only use SafeGuard Enterprise full disk encryption is NOT affected by this issue.

Hi Turim br

Currently, there is no update on the update patch for Safeguard Lan Crypt. Sophos Safeguard Lancrypt will be the end of life on 30th Septemeber, 2019 from our side. Sophos is transitioning future development, maintenance, and support for LAN Crypt to the German encryption specialist conpal GmbH. You can refer to this site for information.

That's not what I'm saying. Someone is actively changing that page (https://community.sophos.com/kb/en-us/134569) I have at least four versions of this page now. I'd like to know what's changing on that page? Are you adding more known issues/changing the patch MSP etc?

Hi MichaelMcLannahan

Sorry for the confusion here. The link to the patch for version 8.00.6 was not publicly live on the Sophos.com which is publically live now on Sophos.com. We have not done any addition to the known issue or resolved issue in the KB article.

Please let us know if you have observed any big change from your side.

Thank you Jasmin. Sadly the fix doesn’t resolve our issue with OneDrive. I have logged this as a ticket (urgent) many days ago but no-one has replied yet.
