Outlook 2016 Calendar view problems with reading pane open

Outlook version
Outlook 2016 64 bit
Email Account
I found a couple of references to this on the web but no solutions.

I have my folder pane set to a specific width in the mail view. If I change to contacts everything looks good, but if I change to calendar view, with the reading pane on the right, the folder pane gets narrow and I can't see all the icons on the bottom. Further, I can't re-size any of the panes. Depending on the circumstances, switching back to mail view may or may not fix the width.

With the reading pane closed, this doesn't happen. Obviously there are work-arounds but this is really annoying when I'm switching between views quickly.

Does anyone have a solution for this?
