He’s saying the “about” button (under the question mark) in OWA is no longer there since they changed the interface. (quite a while ago now)

He’s suggesting using powershell to connect to office 365 and use the get-mailbox commandlet to get this info.

(more info on powershell & o365):

However I’ve found you can get the info from the microsoft remote connectivity analyser.

    Good Day Jak;

    I am sorry, but I don’t understand your comment. I am running on Outlook 2013 and these instructions worked for me. If you can explain your comment and provide more detail, maybe I can help or adjust my post to better fit the situation.

    Thanks for your comments all the same.

I do not see the “about” link below the help

    Ian Matthews · April 15, 2013 at 8:59 pm

    It should be there… if you don’t see it, I would call Microsoft support.
