IMAP does work in Evo, but remember that Google's implementation of
IMAP in Gmail is unusual. Whether that is related to your problem or
not is hard to tell, but I know I did see a positive effect when I
changed to using GOA after many years of having manually configured
Gmail accounts. For one thing updating seemed to be much faster and
less error-prone (though this may have been due to updating Evo to
version 3.16.x). I have no idea why this should be so, but it's
important to note that Evolution is part of the wider Gnome system
(even though I use it under KDE) so other stuff is going on that may
not be directly visible. Perhaps Milan could expand on this.

I was assuming that in any case. If Evo loses connection with an
account it will give a very visible warning.

I presume these are not Gmail accounts? Do you also have any POP
accounts that exhibit the same problem?

One option is to create a completely fresh user on your system, log in
and configure Evolution to access your accounts, then see how it
behaves. To minimize the number of variables, log out of your normal
user account first (or at least shut down Evo). Leave all the
Preferences set to default values and see what happens. Check if the
database error still appears for the new user.

If that still doesn't work I can only suggest you update Evo to the
latest version (3.16.x) if possible.
