Turkish DST Time Zone issue

Hello Team,

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

Thanks,
Andy

You should still be able to use TZEDIT from Microsoft to change the time zone to your needs.

OWA is on a server and that is where you need to adjust the time. OWA is not responsible for time zones, but the servers are.

Did you check client computers to make sure the time zone is correct on the client computers. If clients are correct and server is correct, I do not know why OWA would be wrong.

If you are doing everything correctly, then the incoming email and calendar invites must be off. Consider contacting the senders.
