[Evolution] why Evolution email application unnecessarily prompts for passwords on random occasions.

["James R. Overstreet" <joverstreet1 verizon net>]

Why is it that on random occasions Evolution email application will
start prompting for passwords on EVERY instance of both sending and
receiving emails.

AND then just as suddenly as it started prompting for the passwords, it
will stop this behavior (or should I say mis-behavior), just as suddenly
as it started with nothing having changed as far as any programming of
either Evolution application, operating system or any other program,
and/or data updates to the said computer system.

Am using Evolution version 3.10.4 on a Linux Mint 17.3 operating system
computer with all updates applied as on today.

This problem has been going on for several years now, seems like to me
it is time someone decided to fix it.

Thanks.
