#263 DavMail with Outlook EWS - Plaintext connection issue

[Francesco Giuffrida]

I'm trying to use DavMail with Thunderbird on Linux Mint 17, with my company exchange server 2010 EWS.
I follow the instructions in
http://davmail.sourceforge.net/gettingstarted.html

Unfortunately I constantly get the following erro sequence in the davmail.log

2015-12-21 12:24:07,118 DEBUG [davmail.imap.ImapServer] davmail - Connection from /127.0.0.1 on port 1143
2015-12-21 12:24:08,263 WARN [ImapConnection-45183] davmail.exchange.ExchangeSession - Connect exception: javax.net.ssl.SSLException Unrecognized SSL message, plaintext connection?
2015-12-21 12:24:08,266 WARN [ImapConnection-45183] davmail - DavMail configuration exception:
Connect exception: javax.net.ssl.SSLException Unrecognized SSL message, plaintext connection?
2015-12-21 12:24:08,266 DEBUG [ImapConnection-45183] davmail - > * BAD unable to handle request: DavMail configuration exception: Connect exception: javax.net.ssl.SSLException Unrecognized SSL message, plaintext connection?

As the same confguration works ok for other people, would it be an issue of wrong setup/java version or other packages that are missing in my setup?
My Java version is: java -version
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Server VM (build 25.65-b01, mixed mode)

Any Advice?

Did you enable SSL server certificate in DavMail ?
Yes => make sure your IMAP client is also set to use SSL
No => make sure your IMAP client uses cleartext connection
