Supported Browsers

Microsoft Edge: Office 365 is designed to work with the latest version of the Microsoft Edge browser.

Please note: Internet Explorer is not supported on Windows 10, when using a device with the Windows 10 OS, it is recommended that you use Microsoft Edge, or one of the browsers as listed below. 

Firefox, Chrome, and Safari: Office 365 is designed to work with the current, or immediately previous, version of Firefox, or the current version of Chrome or Safari.  Firefox and Chrome are both designed to stream updates to your device every six weeks.  Many common problems with these browsers are resolved in the next update.

Please note: for those devices that are owned and managed by CSU, the version of Firefox that is installed on these units is not a supported version for use with Office 365.  As such, it is strongly recommended that IE or Chrome be the primary browser of choice when accessing Office 365 via a browser on these devices.
