    there's no solution yet.

    the only workarround is using native device mail apps

    I have also tried rebooting servers and phones, no luck.

    Is anyone else having issues with the iPhone native email client?  It started last night for us, users are complaining about their messages downloading over and over and re-syncing their inbox.

    Did not solve it for me either, but Microsoft know, as I have been writing to them and given them the settings for my ISP.

    Have been messaging talktalk via Twitter, not got very far so far, was asked whether I can log-in to my mail via webmail, will keep people updated of any further development if I get any, as Microsoft say providers need to update to TSL 1.2, let us see if they do. I have tweeted them the link to this thread, by the way.
