I don't receive emails from Hora Finita. What should I do?

If your organisation uses Microsoft Office 365, it often happens that Outlook puts emails from hf@rug.nl in the quarantine folder.
You should check this folder and mark emails from hf@rug.nl as safe.
The quarantine folder containing emails from hf@rug.nl can be found here. How to proceed further can be read here, a simple overview how to handle can be found here. 
To make sure emails of Hora Finita are always delivered, inform your own IT department.
