The educational office365 accounts are only available to active NTHU faculties, staff, and students. 
Starting from Aug 19, the Computer and Communication Center will deactivate the office365 accounts of those who are no longer with NTHU.

Please backup your data because you will no longer be able to log in to your NTHU office365 account.

If you still have another active faculty, staff, or student ID with NTHU, 
Please apply new Office365 account in Academic Information System with your new ID.
