1 – AxCrypt does not by itself control OneDrive operations. It will encrypt files in designated places (semi-)automatically, for example a folder in your local drive that is synchronized with OneDrive. But the actual synchronization to OneDrive is done by OneDrive.
2 – If you are a working as a registered company, you should be using AxCrypt Business – however we won’t come after you if you as a one man operation go with AxCrypt Premium ;-) . Do be aware that we don’t support VAT-free sales with AxCrypt Premium, and if you expand and need to handle several users, we only have a control panel for AxCrypt Business administration. We will be adding other features to AxCrypt Business as well.
