Use of the Kronolith calendar module in Horde/webmail has been deprecated for some time, and a notice announcing its discontinuation has been published on the login screen of webmail.ru.ac.za for at least the last six months.
During the February 2nd maintenance window, this module will be permanently removed. Thus this is your last chance to back-up any calendar entries you have stored in webmail. To do this, click on the pencil icon next to a calendar name to access it's settings, and then choose the Export tab. Save your calendar as an ICS file.
Staff who're not already doing so are encouraged to make use of the Rhodes' branded Google calendar. The same ICS file you exported above can be imported into Google's calendar. Please contact our Help Desk if you need assistance with this.
