The email server is hosted outside the office.
In Thunderbird, under Options->Server Settings there
is an option under "Message Storage" to save the
message mbox files to a "Local Directory".
Rather than saving on the local drive of a given PC,
a user's message files are saved to a samba share on
the network. That shared drive is on a server which
is configured in a RAID setup and has various
files being routinely backed up.
FWIW, this seemed to also occur on a Samba 3 setup
running on Centos. I'm wondering if it's a related
to some kind of file access issue.
Samba Version 4.9.4-Debian
Samba Server Linux Debian GNU/Linux 9 (stretch)
