Steps to reproduce:

Load Outlook web app.  App logs in correctly.

Actual results:

Email works correctly.  Calendar loads but no data.  Loads correctly on 47.0.1 on laptop.  Not a server issue.  Tried in safe-mode but no data

Expected results:

Calendar data populates.
Same problem for me. Tested with the following and all fails to show any data in the calendar.

Tested on Windows 7 x64 with FF 48.0.2, FF Nightly 51.0a1 and I can't reproduce it. Tested with new profile and no add-ons. Please attach a print screen of the issue.

Also try in safe mode.

we had a couple of similar reports from users on sumo after the 48.0 update (so confirming based on that):

chrome had a similar bug once and they had determined it was an issue with exposing Array.prototype.values -

Most likely the same problem as bug 1299593. If anyone in this bug would like to help confirm that we have the right fix for it, you can:

*   Install the mozregression command-line tool:

*   Run this command to download a patched browser:
    mozregression --launch 00eff691634e --repo try

*   Try OWA with that browser and see if it works,
    then let us know what you find. (We expect it to work.)

I am affected by the bug (FF 48, Linux).
Testing with the mozregression build works for me.

Would be nice if this fix could make it into 49 or at least 50. It's quite annoying for us people who have to use Outlook ...
JFYI: Works now in Firefox 50.0b4 (Linux).

 shigman1 has this problem been resolved for you as well?
For me, on 50.1.0 it doesn't. 
It used to show the other Outlook apps lower left, almost like in the 'real thing', now there is only a gray button, for mail.
