We have exchange 2013 and outlook 2013 clients
issue is , after Turkey has decided not to go in Day light saving, means as per standard it need to be UTC + 3:00 istanbul, but in owa for all users it showing as UTC +2:00 istanbul, we have done several testing from owa and because of this Calendar meeting time is affecting, meeting having differences of 1 hours.
I hope you aware of this known issue, as per microsoft, they suggest to release a patch in December by latest. but could you suggest any workaround we can suggest to users
Exactly same issue, we have updated the patch on exchange server , but still in owa regional setting it is not showing as UTC + 3:00 istanbul
