If automatic subscription fails (for example, if you use a different calendar application than what your browser suggests), you will need to subscribe manually.
On the Ημερολόγια page, select a calendar you like.
Click Επιλέγω.
If you are not logged in to WebCal.Guru, you will not be able to modify subscription settings and you will have significantly smaller selection of calendars. In this case, jump directly to Step 4.
Adjust the subscription settings if needed and click Προσθήκη στα ημερολόγιά μου.
You will be taken to Τα ημερολόγια μου page. On the calendar you just added, click next to Λήψη and select Αντιγραφή διεύθυνσης στο πρόχειρο.
Open the Outlook application and make sure you're on the Home tab.
Open the Addmenu and select From Internet…
Click Yes.
