Classroom computers in W&L spaces now have Office 365 installed to provide the most up-to-date feature set and to enable advanced Box functionality such as co-authoring)
Users who launch any Office product (i.e. Microsoft Word, Microsoft Excel, Microsoft PowerPoint, etc.) on a classroom computer will be prompted to authenticate for their initial use.
When launching an Office application the first time, users will encounter this challenge, and should SELECT “SIGN-IN” and proceed. Your Washington & Lee University email and password are the correct credentials to use. 
After authentication in a classroom, subsequent use of Office apps should not require authentication beyond your standard login to the PC.
If you should encounter difficulties after the initial use and authentication, please contact the ITS Helpdesk at help@wlu.edu, call 540.458.4357 (HELP), or stop by the Main Level of Leyburn Library.
