While using kontact in combination with Koloab (kolabnow account) I experience the following problem: I shared some resources (addressbook, calendars, etc) with a second account. While using kontact (korganizer) 4x all works well. I was able to select and display entries of "Other users"-calendar After upgrading to kubuntu 16.04 the "Other Users" entry disappears. For a while a I was able to see the entries anyway. Currently I din't see them either. Displaying and using the "Other Users" addressbook works well instead. Checking "Serverside subscriptions" shows the other user and his folders (checked for synchronisation) I'am using "Kubuntu Backports"
I am also affected by this. Using Kolab with business subscription. Kontact / Calendar is not showing "other users" entries anymore (yet at serverside subscriptions they do show up) using Kontact 5.3.0
Update: open the settings for serverside subscriptions, deactivate all "other users" resources, close the dialog window, reset all "other users" resources again and "voila"... all "other calendars" reappear again. Yet they do not appear within the bottom left "recources widget". I'm assuming the Qt widget was slightly changed and it is not possible to display "nested" checkboxes anymore (previously "other users" resources have been displayed as "nested" items in the checkbox-list)
I can confirm this workaround.
Thank you for reporting this bug in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!
Problem still exisits. Tested with Kontact 5.21.2 (Fresh KDE Neon install this morning) The "Others Users" dosn't appear in the overview, despite the fact, that the subscribed calendars (via Serverside subscriptions) got processed correctly (events are shown, reminders pops up)
