Exchange web service (EWS) says "Accees denied" when I try to delete calendar event created by me

I am trying to delete a calendar event that I have created a while ago.

Case 1:

Case 2

Why can I remove event in Case 1 and I cannot in Case 2? What should I do to delete the event (like in Case 2)?

Here are details of request and responses:

Case 1:

I call EWS to create a calendar event using credentials of domain user [email protected] in some room by providing email address of the room – a meeting like this:
<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\">
      <soap:Body>
            <CreateItem xmlns=\"http://schemas.microsoft.com/exchange/services/2006/messages\" xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\"  SendMeetingInvitations=\"SendToAllAndSaveCopy\" >
                  <SavedItemFolderId>
                        <t:DistinguishedFolderId Id=\"calendar\"/>
                  </SavedItemFolderId>
                  <Items>
                        <t:CalendarItem xmlns=\"http://schemas.microsoft.com/exchange/services/2006/types\">
                              <Subject>Instant Meeting</Subject>
                              <Body BodyType=\"Text\">Generated By mycompany Room Booker</Body>
                              <ReminderIsSet>false</ReminderIsSet>
                              <ReminderMinutesBeforeStart>60</ReminderMinutesBeforeStart>
                              <Start>2015-10-01T10:26:02.000Z</Start>
                              <End>2015-10-01T10:41:02.000Z</End>
                              <IsAllDayEvent>false</IsAllDayEvent>
                              <LegacyFreeBusyStatus>Busy</LegacyFreeBusyStatus>
                              <RequiredAttendees>
                                    <Attendee>
                                          <Mailbox>
                                                <EmailAddress>[email protected]</EmailAddress>
                                          </Mailbox>
                                    </Attendee>
                              </RequiredAttendees>
                        </t:CalendarItem>
                  </Items>
            </CreateItem>
      </soap:Body>
</soap:Envelope> 

then meeting is accepted and I get ItemID like:

state.ChangeKey: "DwAAABYAAADw3LMNr7pMRqtEFFAbr0MeAAAAhxz0"        
state.Id: "AAASAGJyb29tQGluZnVzaW9uLmNvbQBGAAAAAAB5mlhabHe9S4yVHCob9IbcBwDw3LMNr7pMRqtEFFAbr0MeAAAAOdnlAADw3LMNr7pMRqtEFFAbr0MeAAAAhrdWAAA="                

Then I delete the event by calling EWS and providing Id and ChangeKey:

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:m=\"http://schemas.microsoft.com/exchange/services/2006/messages\" xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">
      <soap:Header/>
      <soap:Body>
            <m:DeleteItem DeleteType=\"MoveToDeletedItems\" SendMeetingCancellations=\"SendToAllAndSaveCopy\">
                  <m:ItemIds>
                        <t:ItemId Id=\"AAASAGJyb29tQGluZnVzaW9uLmNvbQBGAAAAAAB5mlhabHe9S4yVHCob9IbcBwDw3LMNr7pMRqtEFFAbr0MeAAAAOdnlAADw3LMNr7pMRqtEFFAbr0MeAAAAhrdWAAA=\" ChangeKey=\"DwAAABYAAADw3LMNr7pMRqtEFFAbr0MeAAAAhxz0\"/>
                  </m:ItemIds>
            </m:DeleteItem>
      </soap:Body>
</soap:Envelope>

and all is fine. The event is deleted.

Case 2:

But when I create event the same way and get response like this:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <h:ServerVersionInfo MajorVersion="14" MinorVersion="3" MajorBuildNumber="235" MinorBuildNumber="1" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />
  </s:Header>
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <m:CreateItemResponse xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
      <m:ResponseMessages>
        <m:CreateItemResponseMessage ResponseClass="Success">
          <m:ResponseCode>NoError</m:ResponseCode>
          <m:Items>
            <t:CalendarItem>
              <t:ItemId Id="AAASAGJyb29tQGluZnVzaW9uLmNvbQBGAAAAAAB5mlhabHe9S4yVHCob9IbcBwDw3LMNr7pMRqtEFFAbr0MeAAAAOdnlAADw3LMNr7pMRqtEFFAbr0MeAAAAhrdYAAA=" ChangeKey="DwAAABYAAADw3LMNr7pMRqtEFFAbr0MeAAAAhx08" />
            </t:CalendarItem>
          </m:Items>
        </m:CreateItemResponseMessage>
      </m:ResponseMessages>
    </m:CreateItemResponse>
  </s:Body>
</s:Envelope>

and when I list calendar events for this room like below:

To be able to call DeleteItem I need this Id in EwsLegacyId format instead of HexEntryId format, so I call ConvertId method:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Header>
            <t:RequestServerVersion Version="Exchange2010" />
      </soap:Header>
      <soap:Body>
            <m:ConvertId DestinationFormat="EwsLegacyId">
                  <m:SourceIds>
                        <t:AlternateId Format="HexEntryId" Id="00000000B23AEBAC6379B34DBBBA0B525D2BBFD70700C26EC63E0E9E2A49B110258061BF491D000000FDECCA0000C26EC63E0E9E2A49B110258061BF491D0000D9385B940000"   Mailbox="[email protected]" />
                  </m:SourceIds>
            </m:ConvertId>
      </soap:Body>
</soap:Envelope>

and I get

And when I try to call DeleteItem on this Id like this:

                  </m:ItemIds>
            </m:DeleteItem>

In Case 1 your deleting the Appointment from your calendar which you have Full Access to. In Case2 it looks like your trying to delete the appointment from the Room Mailbox which you may or may not have Full rights to (the default is read only even if you are the organizer of the appointment its the calendar itself you would need rights to). In the case where you where the organizer of said appointment you would be better to just cancel the appointment in your calendar and send the cancellation through to the Room mailbox and let the auto-accept on the Room mailbox process and perform the delete that way or you would need to assign the mailbox that is trying to do the Delete Full access to the Room mailbox in question.
