Created attachment 143402 [details] modal errors SUMMARY I had troubles connecting to Office365 using EWS so I use its calendar via process described in Steps to Reproduce. Problems here are: - I have duplicated events in my calendar. - I see many modal windows errors. I'm presented with about 30 modal window errors and it is complicated to close them, because they need to be closed in LIFO order and they overlap. See screenshot. STEPS TO REPRODUCE 1. Create a calendar in Office365 with some recurring events 2. In Office365 create a unique download URL for your calendar 3. Download calendar as .ics 4. Create new calendar in KOrganizer using iCal Calendar File and keep checked Enable File Monitoring 5. After some time download new version of .ics and replace file you imported in step 4. OBSERVED RESULT - I have duplicated events in my calendar. - I see many modal windows errors. EXPECTED RESULT Calendar is imported without errors or at least there is one more helpful error message.
