If you have not yet activated the Office365 service, you can do so by following these instructions:

To start using the service, you need to create an account at the following link

https://www.microsoft.com/en-us/education/products/office

Important note: when creating an account, you must enter the username of your AAI@EduHr identity (e.g., pperic@pbf.hr) so that the system recognizes you as a user covered by the service.

After that, you also need to create a password that you will need in the future (together with this username) to access the service.
