Firstly, the ticket above is still open and unanswered…
I’ve just upgraded to v8 and have a couple of problems.
Red triangles on an Office365 Exchange account. Error message in the log is:
09:34:55 —> System.ArgumentException: The DateStart property must come before the DateEnd property. (Parameter ‘dateStart’)
Also, when settings an appointment in the Exchange calendar I get the following error:
[Exchange Web Services] The specified time zone isn’t valid., The specified time zone isn’t valid.
If I add a time zone to the appointment it doesn’t “stick” and the error reappears.
