I am trying to share a directory with a user on another ownCloud server. However, this user has a space in his username (
Firstname Lastname). So, instead of sharing the directory with
firstname.lastname@example.org (which works, we've tried with another user without spaces), it seems I should share it with
Firstname Lastname@urltoowncloudserver.com. My problem is that this URL is not accepted by my ownCloud server. What is the correct way (if any) to share with this user?
