When you join the University you will be given a University of Edinburgh (UoE) email account and address which will be used for a variety of essential communications. You must access and manage this account regularly as the University will send you vital information from time to time, for example on assessment arrangements or changed class times or locations, and will assume that you have opened and acted on these communications. Failure to do so will not be an acceptable excuse or ground for appeal.
If you already have a web-based e-mail account and think that you are unlikely to check your UoE e-mail account, it is your responsibility to set up a forward on the UoE account to ensure that all official University communications are received. There are on-screen instructions if you wish to do so: please see http://www.ed.ac.uk/schools-departments/information-services/services/computing/comms-and-collab/email/sms
You can locate your email by logging into EASE. http://www.ease.ed.ac.uk
