    I installed gmail and that has fixed the issue.  Well done Microsoft another fan is now converted.

    Same problem here.

    All android devices since yesterday keeps showing certificate error popup without any system change and with a valid certificate.

    I also added my own CA to CA store in the android device without any luck.

    With Exchange 2007 too.

    No workarround yet.

    Thanks.

    This has happened to me, both on the IPhone and IPad with tiscali email, settings have not changed. Microsoft need to sort this out, as it appears a lot of us like using Outlook rather than the mail app from Apple.

    This is also happening to me.

    It is only affecting Android Mobile.

    Clicking the Login option from the dialog to login anyway doesn't do anything.

    This started today 4/25.

    I have uninstalled / reinstalled.
