Lx-Office has been switched to group-based access restrictions. You have to create at least one group, grant it access to Lx-Office's functions and assign users to it. Otherwise all users will only have access to their own settings.
During this user migration Lx-Office can create such a group for you and grant all users access to all of Lx-Office's functions. This corresponds to Lx-Office's behavior prior to version 2.4.4.
Alternatively you can skip this step and create groups yourself.
Do you want Lx-Office to create a group for access to all functions? This group will be called "Full Access".
