Hi All
I have researched for this issue and am unable to find a solution.

Updated Appointment via EWS shows UTC instead of local TZ in attendee's calender event notification mail

Here is what's wrong:
in when it showing time in UTC instead of local timezone ie (UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi . both timing has 05:30 difference so it create confusion,Both timing should be same.

@itbw please look into this issue

@rajeshpatil1012 I think this is related to #357.

• According to https://msdn.microsoft.com/en-US/library/office/Dn789029%28v=EXCHG.150%29.aspx, if StartTimeZoneDefinition is not provided, Exchange server interpretes StartTime as UTC.
• I think the following things had happened:
  • Start TimeZone was set to "India Standard Time"
  • ews-java-api library fails to created proper TimeZoneDefinition
  • Appointment will be written anyway, but the time will be set as UTC
• I'm working on bug from How to use setStartTimeZone method of Appointment class? #357, so when it will be fixed, this one should be fixed too.

Hi @itbw i tried following code in ServiceRequestBase.java class just giving hard coded value then i got correct result
when try whih dynamic value setting bias i have issue, how to set Bias in this java file
I think that is only option to change api ServiceRequestBase.java file to set correct time in notification mail in java

I'm currently using 2.1-snapshot but still have same bug, how to disable when message in body, i set start and end time zone but still message is UTC format

            Appointment meeting = new Appointment(exchangeSender.service);
            // Set the properties on the meeting object to create the meeting.
            TimeZoneDefinition td = null
            exchangeSender.service.serverTimeZones.each {
                if (it.id.equals("Turkey Standard Time")) {
                    td = it
                } 
            }
            meeting.subject = args.subject;
            meeting.body = new MessageBody(args.body)
            meeting.start = args.start
            meeting.end = args.end
            meeting.location = args.location
            meeting.isAllDayEvent = false

// meeting.startTimeZone = new OlsonTimeZoneDefinition(TimeZone.getTimeZone('Europe/Istanbul'))
// meeting.endTimeZone = new OlsonTimeZoneDefinition(TimeZone.getTimeZone('Europe/Istanbul'))
meeting.startTimeZone = td
meeting.endTimeZone = td

I am also using 2.1-snapshot and I observed same issue in meeting invitation while creating appointment not only while updating.

[selamialtin]

I changed exchange version to Exchange2007_SP1 and solved problem also set only startTimeZone like this. I hope this will help you.

exchangeSender.service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
Appointment meeting = new Appointment(exchangeSender.service);
meeting.subject = args.subject;
meeting.body = new MessageBody(args.body)
meeting.start = args.start
meeting.end = args.end
meeting.location = args.location
meeting.isAllDayEvent = false
meeting.startTimeZone = new OlsonTimeZoneDefinition(TimeZone.getTimeZone('Europe/Istanbul'))
meeting.reminderMinutesBeforeStart = 15;

[Prathyushasdp]

@selamialtin thanks for your suggestion

I am dealing with Microsoft Exchange server 2010 SP2 so I have to use ExchangeVersion.Exchange2010_SP2 to get exchange service otherwise I can not perform other operations

[selamialtin]

Yes, we are using excahge server 2010 sp2 too, you should use the ews service as ExchangeVersion.Exchange2007_SP1 while sending appointment, no problem.

[Prathyushasdp]

@selamialtin thank you so much. It is working after setting ExchangeVersion.Exchange2007_SP1 while sending appointment.

Hi All
I have researched for this issue and am unable to find a solution.

Updated Appointment via EWS shows UTC instead of local TZ in attendee's calender event notification mail

Here is what's wrong:
in when it showing time in UTC instead of local timezone ie (UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi . both timing has 05:30 difference so it create confusion,Both timing should be same.

How did this problem be solved?
