--- Comment #14 from John D Nash <jdn...@jdnash.com> --- I tried to restart testing. I installed Version: 7.2.0.4 / LibreOffice Community Build ID: 9a9c6381e3f7a62afc1329bd359cc48accb6435b Under tools / options / writer / mail merge email I can not find a combination that will work. I tried my corporate email credentials on Office365 and my corporate credentials for google.com. I am copying the credentials and server settings from Thunderbird, where they do work. When I reported Bug 139072 in December 2020 I successfully connected to email the first time. I'm stuck and can not run further test unless I can get the email to connect. What am I missing? error report is: LibreOffice could not connect to the outgoing mail server. Check your system's settings and the settings in LibreOffice. Check the server name, the port and the secure connections settings -- <class 'imaplib.IMAP4.abort'>: unexpected response: b'220 CH0PR03CA0223.outlook.office365.com Microsoft ESMTP MAIL Service ready at Tue, 31 Aug 2021 20:07:00 +0000', traceback follows File "/opt/libreoffice7.2/program/mailmerge.py", line 315, in connect self.server = imaplib.IMAP4(server, port) File "/opt/libreoffice7.2/program/python-core-3.8.10/lib/imaplib.py", line 201, in __init__ self._connect() File "/opt/libreoffice7.2/program/python-core-3.8.10/lib/imaplib.py", line 243, in _connect self.welcome = self._get_response() File "/opt/libreoffice7.2/program/python-core-3.8.10/lib/imaplib.py", line 1079, in _get_response raise self.abort("unexpected response: %r" % resp) -- You are receiving this mail because: You are the assignee for the bug.
