I just installed Outlook v15.9 as well as updates for the entire new Mac 2016 suite released yesterday. I'm getting an Outlook certificate error as can be seen in the attached screen shot. I can click Continue and run Outlook without any problems and it works fine. Also, I wasn't getting this error in the immediate prior release. All of my company's email is hosted on Office 365. How can I fix this or should I worry about it? Thx! John

    Hello John,

    I believe your O365 tenant is redpoint.net. If this is correct, just open a browser and visit https://redpoint.com and see if you see the same certificate issue?

    Thanks,

    I get the same issue.  Only started with 15.9.  Microsoft hosted Office 365.

    Thanks,

    Chris

    Pawan,

    I only get this certificate issue with this newest version 15.9 of Outlook for Mac.  All my other Apps accessing the internet and redpoint.net including my browser are fine.  Looks like another user below is also seeing the same issue.

    I'm having the same issue.  Hostmoster is hosting our domain milesarch.com.  Exchange is O365.

    Same issue here after installing 15.9.

    Host name mismatch.

    If I click continue, Outlook works for a while, but then it hangs and sometimes I have to force quit it.
