I'm using the EWS API (targeting Exchange 2010) I cannot figure out why anything I make a request to update a calendar meeting/item. Is there something I'm missing or is this the expected behavior? I'm able to make a change from Outlook to the meeting without it sending out a cancellation email to all attendees except the organizer.
The below is a sample of the relevant portion of the SOAP request. I replaced the actual attendee's email addresses, item ID and change key.
{:send_meeting_invitations_or_cancellations=>"SendOnlyToChanged",:conflict_resolution=>"AutoResolve", :item_changes=>[{:updates=>[{:set_item_field=>{:field_uRI=>{:field_uRI=>"item:Subject"},
:calendar_item=>{:sub_elements=>[{:subject=>{:text=>"Thursday 11AM Recurring"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"item:Body"}, :calendar_item=>{:sub_elements=>[{:body=>{"BodyType"=>"HTML", :text=>"HI"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:Location"},:calendar_item=>{:sub_elements=>[{:location=>{:text=>"LA, CA"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:Start"}, :calendar_item=>{:sub_elements=>[{:start=>{:text=>"2019-03-07T19:00:00.0000000"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:StartTimeZone"}, :calendar_item=>{:sub_elements=>[{:start_time_zone=>{"Id"=>"UTC"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:End"}, :calendar_item=>{:sub_elements=>[{:end=>{:text=>"2019-03-07T19:30:00.0000000"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:EndTimeZone"},:calendar_item=>{:sub_elements=>[{:end_time_zone=>{"Id"=>"UTC"}}]}}},
{:set_item_field=>{:field_uRI=>{:field_uRI=>"calendar:RequiredAttendees"},:calendar_item=>{:sub_elements=>[{:required_attendees=>{:sub_elements=>[
{:mailbox=>{:name=>"Joe ABC",:email_address=>"[email protected]", :routing_Type=>"SMTP"}},
{:mailbox=>{:name=>"John ABC", :email_address=>"[email protected]",:routing_Type=>"SMTP"}}]}}]}}}],
:item_id=>{:id=>"AAMkAGJjNWIzNzI2LTM1N2YtNDVkMi05NzU5LTRj",
:change_key=>"DwAAABYAAADWK9s0Y5iSSLP"}}]}
