A number of my users are getting the following error when trying to use the latest Office365 update

X-OWA-Error: ClientError;exMsg=Script error.;file=https://r4.res.outlook.com/owa/15.0.745.25/owa2/scripts/boot.1.mouse.js:0 X-OWA-Version: 15.0.745.25 X-FEServer: AMXPR04CA002 X-BEServer: null Date: 02/01/1601 14:16:51

Native client tools seem to be okay, just 3rd party browsers (we have the same issue with Safari and Chrome). I am assuming that Microsoft have introduced some function with their update last Tuesday/Weds evening.

Nothing on the microsoft site, any help greatly appreciated.

I'm Using Microsoft Outlook web app, I'm not facing any issues.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

To Enable SafeMode

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
  • Once you get the pop-up, just select "'Start in Safe Mode"

If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")
