I have a user who is having problems with outlook 2016. Everytime they add a new folder one of two things happen
1) There is a space appear underneath the new folder
2) The next two folders in the list appear on top of each other scrambling the folder names.
To fix it they have to restart outlook.
There is a folder in the space because they can click on the space and it goes to a folder but the name is not being displayed.
They are using the client as POP3.
I have attached image as example.
