Unable to encrypt Lumia 640 after reverting from Windows Phone 10 RRS feed

  • Question

  • Dear all,

    Has anybody managed to solve this issue? After downgrading from Windows Phone 10 to 8.1 on my MS Lumia 640 my phone is unable to encrypt (we are using AirWalk MDM client). I decided to downgrade from 10 to 8.1 as with 10 my phone was really unstable, often crashing or freezing, thus rendering it unusable for business purposes. Now, being unable to sync my Office 365-based e-mail with my phone is pretty much useless as well! Obviously I have tried all kinds of resets (soft-hard), re-installing it from scratch without restore etc but the issue remains.

    Many thanks in advance for any assistance!
