[Evolution] Moved messages disappear from source, never show in destination

[Matthew Saltzman <mjs clemson edu>]

I have an EWS account--I don't know if it's an issue with other types. 

Sometimes (but not always) when I select a block of messages and move
them from my inbox to another folder, the messages are removed from the
list in the inbox but are not moved to the destination folder. I access
the account with evolution on multiple machines, and each time I see the
messages in my inbox, but when I try to move them, they fail to move. 

Accessing the account via a browser shows that the messages are still in
my inbox, but no amount of syncing (send/receive button or refresh
option in the right-click menu on the account or the folder) short of
deleting and recreating the account gets them to show in Evolution in a
client where I tried the move.

This occurs in Evolution 3.12.11 on CentOS 7 and 3.18.5.2 on Fedora 23.
(But I had the problem once before, a couple of years ago. I had given
the messages up for lost, but they suddenly reappeared when I created
the account on another client machine.)

Bug, or PEBKAC?

TIA.
