After installing thunderbird in Linux Mint with cinnamon I set the mailfolders to a netwok share.

I did this in windows (z: drive) and this never got forgotten. Now it insist on using a run directory. After changing to a new network this setting is lost.

Must be: /net/server5/home/user/mail/pop3.robkalmeijer.nl
Is: /run/flatpak/doc/f6965ebd/pop3.robkalmeijer.nl

Is accept when I change it but keep showing the /run/..... which is a virtual directory.

Option change this as in windows so it keep showing what I selected.

If link is not available it must be ignored as in windows.

Working:
I use a server in my LAN with NFS shares which is mounted at start.
I installed wireguard which must always be running.
