Office 365 Sync Timezone Problem

Office 365 Calendar synchronization returns the following error:

15:37:52 Feroks [Exchange Web Services]  MailClient.Accounts.ConnectionException: Invalid timezone. Id: Turkey Standard Time, DisplayName: (UTC+03:00) Istanbul, Standard name: Standard, Daylight name: null —> System.ArgumentException: Invalid timezone. Id: Turkey Standard Time, DisplayName: (UTC+03:00) Istanbul, Standard name: Standard, Daylight name: null —> System.ArgumentNullException: Value cannot be null.

My timezone (Turkey Standard Time) has no Daylight Savings Time, though this change has been implemented last year.

I am wondering whether this error occurs for other timezones that have no DST, like UTC+03:00 Minsk, Moscow and Kuwait.

Screenshots are below:
