I am using the Java EWS library to search for appointments in a user's calendar by iCalUid
(example iCalUid
I have: 040000008200E00074C5B7101A82E00800000000F66E2C0D59A9D001000000000000000010000000F7A6AACB779B00429164F39AE6DD6BB9
). Here is my Scala code:
import microsoft.exchange.webservices.data._
import java.net.URI
import java.util.Date
val exchange = {
val service = new ExchangeService(ExchangeVersion.Exchange2010_SP2)
service.setUrl(new URI(host))
service.setCredentials(new WebCredentials(user, pass))
service
}
def calendarFolderFor(email: String) = new FolderId(WellKnownFolderName.Calendar, Mailbox.getMailboxFromString(email))
def findMatchingAppointments(iCalUid: String, email: String) = {
val searchFilter = new SearchFilter.IsEqualTo(AppointmentSchema.ICalUid, iCalUid)
exchange.findItems(calendarFolderFor(email), searchFilter, new ItemView(1)).getItems
}
The above code throws this error:
microsoft.exchange.webservices.data.ServiceResponseException: The property can not be used with this type of restriction.
at microsoft.exchange.webservices.data.ServiceResponse.internalThrowIfNecessary(ServiceResponse.java:262) ~[ews-java-api-1.3-SNAPSHOT.jar:na]

at microsoft.exchange.webservices.data.ExchangeService.findItems(ExchangeService.java:851) ~[ews-java-api-1.3-SNAPSHOT.jar:na]
I then tried adapting the code from this thread:
def findMatchingAppointments(iCalUid: String, email: String) = {
import org.apache.commons.codec.binary.{Hex, Base64}
val searchFilter = new SearchFilter.IsEqualTo(
new ExtendedPropertyDefinition(DefaultExtendedPropertySet.Appointment, 0x03, MapiPropertyType.Binary),
Base64.encodeBase64String(Hex.decodeHex(iCalUid.toCharArray))
)
val view = new ItemView(1)
view.setPropertySet(new PropertySet(BasePropertySet.FirstClassProperties, AppointmentSchema.ICalUid))
exchange.findItems(calendarFolderFor(email), searchFilter, view).getItems
}
But, now it does not throw an exception but it does not find the appointment either. I know the appointment exists because I brute-forced and found the appointment using this snippet of code:
def bruteForceFind(start: Date, end: Date, iCalUid: String, email: String) = {
val view = new CalendarView(start, end, 100)
exchange.findAppointments(calendarFolderFor(email), view).getItems
val allAppointments = exchange.findAppointments(calendarFolderFor(email), view).getItems
allAppointments.filter(_.getICalUid == iCalUid)
}
What am I doing wrong? How can I search for appointments for a user given the iCalUid? Working Java/Scala code is okay too.
Apparently there is a difference between a meeting and an appointment. Replacing this line:
new ExtendedPropertyDefinition(DefaultExtendedPropertySet.Appointment, 0x03, MapiPropertyType.Binary),
with
new ExtendedPropertyDefinition(DefaultExtendedPropertySet.Meeting, 0x03, MapiPropertyType.Binary)
works.
