In Most instances this is handled by the University Microsoft managed email address and has nothing to do with/cannot be accessed or installed by Study Tech or other DSA AT suppliers.
Exceptions can/are made for distance learning/network students.
Some Universities or higher education providers do not qualify.
If you have been provided a product key for Microsoft Office, still try the methods below to activate your product before trying the "manual methods" listed last in this article.
This email account is also needed if you
wish to reinstall your Microsoft Office and need to activate it again.
[Activate Office]
To activate your Microsoft Office 365,
simply launch a Microsoft Office application i.e. Microsoft Word. Then follow
the on-screen instructions.
In most instances we advise that you NOT apply the Organisation (University) policies when installing Office as this has caused conflicts in the past/can lead to you being unable to access full administrator privileges on your device.
You will still be able to access your apps/Office on that second profile/Administrative user in most instances.
Office 365 and Apple Mac's, and/or Universities where the office 365 license is unavailable or not set up.
We are not sure why, but we see a lot of instances of the Apple/Mac version of 365 being incorrectly setup/not setup at all by Universities.
In that instance, usually a serial key version of the product is your best bet, as Uni tech support will usually be unwilling to help if the number of Mac users at the University is low.
It is possible to get cheaper keys from sites like Groupon for less than £10, however these will be "Gray Market" OEM keys, not actually designed for consumers and there will be extra steps involved in activation/actually getting a key, usually via a two set key and security code for a random website.
While we do know this works, have never had a student/anyone say they have not received the product and is not illegal it is something Microsoft are known to frown on.
However, we know of no other downsides, save that the license will be machine specific and non transferable in most instances.
We would be unable to offer any assistance with these keys in most instances, but note again that if instructions are followed they seem to work with no issues.
Using a serial key to activate Office 2019, 2021 or 2024.
[Assistance]
If you require
any assistance, please don’t hesitate to contact our Study Tech Technical Support Team.
However, for most enquiries it will make more sense to search the knowledge base first, contact your University Tech support, as they will have to action any Office 365/keyless install query or contact Microsoft themselves if an account issue.
