To start off, you need to retrieve your iCal Calendar Subscription link. The required steps are the same for all users - so if you wanted to subscribe to a colleagues calendar, get them to follow these steps and send you the link.
- In the top right-hand corner of Rex, click on the icon that shows your initials (eg "RT") or your Profile Picture
- Choose My Settings
- On the Left, choose My Details
- At the bottom, you should see 'You iCal Calendar Subscription Link'
For information on setting up your iCal link, take a look at our help content.
