Storing individual messages in individual files, sacrosanct and
unedited, is part of the basic IMAP specification. I agree that an
additional database is usually cunnecessary. It can break down when
too many thousands of files are all in the same folder, but that's
easily handled by splitting off filders by date sent of the files
contained therein.

There are too many robust clients for IMAP to even number. I was fond
of the old "Pine" software, and used to organize hooks to enable SSL
for IMAPS for the public versions. "outlook.office365.com" does
indicate that it's the Office365 services, which are allegedly IMAP
compliant. I'd urge you to KISS: don't try ti import software such as
"davmail" what has apparently only ever been supported under Ubuntu,
do *not* use Java for an enitrely unnecessary "mail gateway". Work
with the simplest, most robust IMAP client you can find:

I admit that I switched my mail handling to Gmail some time back, for
stability and well supported access of bulky email. Thunderbird used
to be pretty good, and I used it recently to iron out some confusion
with an upstream Office365 service. It gave me a much more accessible
look at the older mail to have local copies of everything in
analyzable folders.
