[Evolution] Evolution Calendar not getting synced reliably

["Taborsky, Jiri" <Jiri Taborsky acision com>]

I am having problem with Evolution Calendar connecting to Office365 via EWS that not all meetings are not shown. Majority of meetings are present, but some random meetings are not shown (they are visible in O365 web calendar, but not in Evolution Calendar).
 Refreshing Evolution Calendar does not help. I set "Automatically synchronize remote e-mail locally" option and few meetings appear in Calendar, but still not all of them, hence using Evolution Calendar is not reliable.

Not sure if this is related, but I set also options "Check for new messages every 1 minutes", "Check for new messages in all folders" and "Listen for server change notifications" for related e-mail account.
