X-OWA-Error: ClientError;exMsg=A mutation operation was attempted on a database that did not allow mutations.;file=_a.UserAgent.prototype.get_$3uO@https://server/owa/prem/15.0.1104.5/scripts/boot.0.mouse.js:82:552661
I have the same problem with another servers which are 2010. So the problem is local on my computer with FF 39. Clearing cookies not helped.		

Firefox 39 works fine for me, logging in to my Office 365 mailbox.  You might start trying removing add-ons and plug-ins.

Hi,

I understand you have the display issue on OWA when using Firefox 39.

Please confirm whether the issue happens to all users or specific users to narrow the issue to client side or server side.

According to your description, the issue seem to being related to the client side.

Please try to use other browser like Chrome or IE to check if the issue persists.

We can also use other version Firefox to test.

David
