Exchange EWS ChangeType always "Created" - exchange-server

We are working on synchronizing our outlook-calendar with our custom web application.
We have set up an exchange-server for testing and we are able to get the calendar-items out of the calender.
The problem is that the ChangeType is always "Created" (although we changed some-values with the outlook-Client from Microsoft).
The code to get the items is the following:
ChangeCollection<ItemChange> calendarChangeItems =
service.SyncFolderItems(folderId, PropertySet.FirstClassProperties, null,512, SyncFolderItemsScope.NormalItems, null);
Any ideas?

This link helps me to understand the meaning of SyncFolderItems:
How to get required attendees in SyncFolderItems method
Very important is to keep the SyncState for further synchronisations.
Thank you for help.

Invalid Named Property

We call the microsoft exchange to set the extended property which in our case is an unique guid
microsoft.exchange.webservices.data.core.exception.service.remote.ServiceResponseException: An internal server error occurred. The operation failed., Invalid named property
Its been working great until now when some of our users are facing the above issue ....
val uId = getUniqueId();
val emailExtendedPropDef = new ExtendedPropertyDefinition(uId,"uniqueId", MapiPropertyType.String)
try {
email.setExtendedProperty(emailExtendedPropDef, uId.toString)
email.sendAndSaveCopy()
} catch {
case e: Exception =>
error(s"Exception in setting extended property for user $from", e)
throw e
}
trying to find the root cause of the issue, we are also thinking it might be related to throttling on Microsoft exchange for extended properties (Not sure how to prove if it's indeed throttling) any help to point us in the right direction will be of great help
Our use case is to able to retrieve the email when customer want's to reply back we want to retrieve that particular email to be included in users reply....currently we are using the uid to achieve that ....
we have been using the code as per the documentation here
https://learn.microsoft.com/en-us/previous-versions/office/developer/exchange-server-2010/dd633654(v%3Dexchg.80)
and also the documentation here
https://github.com/OfficeDev/ews-java-api/wiki/Getting-Started-Guide#extended-properties
Update : As per the comments we do understand that we have to treat extendedProperty as a column definition and update the same column ...but we couldn't figure out how to achieve this as...Any code samples to point us in the right direction will be of great help
Latest Update : We have deleted some of the extendedPropertyDefinition's but still facing the same invalid property could some one please point us in the right direction
Is it safe to say that getUniqueId returns a different guid on each call? If so, then that is the problem. Think of the Guid for an extended prop as a namespace. The exchange store limits the number of custom extended props to something like 32k per mailbox. So you are likely hitting that limit. But aside from that, the main reason for creating an extended property is so that you can refer to it later. But if you are basically discarding the namespace each time, you are leaving orphaned props on items. Without understanding your particular scenario, I can only say that the Guid should be thought of truly as a namespace. Choose one for your app/company/scenario and hard code it. They create all the named props you want within that namespace. For instance, "MyProp/String" in Guid namespace 1 is a different property than "MyProp/String" in Guid namespace 2.

Google Drive API Folder/Child ID

Does anyone knows if the google folder id changes over time? Assuming, obviously, the folder is not deleted and recreated.
I'm trying to be limit the quota usage as much as possible, by storing the ID on our side.
Thanks
UPDATE (2015/09/01) Per 'BSEs' comment below.
Sorry, I assumed it is Android (being professionally distorted).
Anyway, to make sure, look at the ID string in question and compare it with the ID you get from drive.google.com > right click > Get link. You should see something like:
https://drive.google.com/open?id=0B1mqwertyasdfghZxCvbItM0E
If the id= string matches your resource ID, you're cool. Sorry for the confusion.
ORIGINAL (incorrect for .NET, applies to GooPlaySvcs/GDAA on Android)
I believe it does.
When testing the ResourceId availability here, I remember getting DriveId in one form immediately in the 'onResult()' callback. Later, when the 'onCompletion()' event occured, the DriveId of the same object looked very different (applies to both file and folder) .
Also, look at Daniel's comment here, it suggests that you should not rely on the value of the DriveId in any moment and use 'equals()'.
The ResourceId would be more appropriate ID to store, shuttle around, etc... DriveId is useless outside the GooPlaySvcs instance. And, based on some hints from Drive-Involved-Googlers, relying on a concrete value of DriveId is dangerous. That makes existence of 'encodeToString() / decodeFromString()' somewhat questionable, right?
Good Luck

Exchange Managed API: Get Resources List of an appointment

I am creating a utility to get sync room calendar with my application.
They way i do is by calling syncfolderitems function for the room I want to sync.
Issue:
Since a User creates an Appointment and we are syncing room calendar thus we are not able to fetch value for Resources property. After doing some research I found that there is an extended property that can be used to find all attendees (Rooms are also attendees) of appointment.
Extended property was "PidLidAllAttendeesString".
Issue with this property is that it returns all the attendees of an appointment (Sendable and Unsendable both).
Is there any property that contains only Sendable attendees data ?
Based on [MS-OXPROPS], PidLidToAttendeesString "Contains a list of all of the sendable attendees who are also required attendees." Downloading the PDF of [MS-OXPROPS] and searching on "sendable" or "resource" might yield some other options too. Hope that helps!

Breeze validation messages are not production ready

Breeze's default validation messages use the database field name as part of the displayed error message; such as, "EmpTeleNo is required". Obviously, this probably shouldn't end up in the production version of our software.
But as we approach delivery of our software, it was hoped that this might be fixed, perhaps by inspecting the "Display" attribute from the model or something like that. As far as I can tell, this issue still remains.
Has this problem been resolved or has anyone figured out a work-around?
Thanks.
This is not YET well documented but you can simply set the 'displayName' property on any dataProperty and this will override the autogenerated display name and will be used for all validation messages for this property. So
var custType = myEntityManager.metadataStore.getEntityType("Customer");
var dp = custType.getProperty("companyName");
dp.displayName = "My custom display name";
Also, see the "Customize the message templates" topic at the bottom of this page: http://www.breezejs.com/documentation/validation.
There is also an item on the Breeze User Voice that requests something very similar to what you are asking for. Please vote for it.

Read Only Error on incident form in plugin CRM 2011 Plugin

I have a problem, which I'm really trying to figure out how I could best solve this. I have read various posts regarding this error and seems you can avoid this by using JavaScript by using:
Xrm.Page.getAttribute("name").setSubmitMode("always");
which doesn't work for me or inside the plugin. Now to my problem, I have an update plugin firing on my incident form, which updates some fields. However when I try to resolve the case or cancel it I get the error from my update plugin "The object cannot be updated because it is read-only" I have tried the following and would appreciate if somone could advice me what I'm doing wrong. My code for a plugin I'm registering as SetState on pre-operation against the incident form:
SetStateRequest setState = new SetStateRequest();
setState.EntityMoniker = new EntityReference();
setState.EntityMoniker.Id = incidentId; //Id which needs to be resolved/canceld
setState.EntityMoniker.Name = "statecode";
setState.EntityMoniker.LogicalName = "incident";
setState.State = new OptionSetValue();
setState.Status = new OptionSetValue();
SetStateResponse setStateResponse = (SetStateResponse)service.Execute(setState); }
On the state and status I'm quite confused to what value I have to set it to. I'm just getting an error when my incident is on Active and I'm trying to resolve and cancel the case. I would appreciate if someone could help me out here. Thanks in advance.
I think there are a few areas of confusion in your post...
Xrm.Page.getAttribute("name").setSubmitMode("always");
This is clientside code and will never have any bearing on the behaviour of your (serverside) plugin. It merely forces an attribute on the form to be submitted whether it has changed or not, during a save. If the record is in a read-only state, it will not change that fact.
I'm not at all clear what you are trying to acheive in your code. You mention that an update plugin is failing; you have posted code which would attempt to set the state of the incident to something (as #glosrob suggests, you are not providing any values in the OptionSetValue objects for State and Status so as you might already know, the code you have posted is invalid); you then state that you have registered your plugin on the SetState request. This means that it would fire if the user tries to set the state of the incident. Given that your code is itself trying to set the status of the incident, I'm not sure that it makes sense...
It sounds like what you want to do is, on update of an incident, set certain values. If the incident is in a read-only state, make it readable first, and then update the values. Do you then need to restore the state of the entity to it's former state? It sounds awkward and might perhaps suggest that there is a better way to meet your core requirement.
Maybe start with what you are trying to achieve and we can work from there :)
You should remove
setState.EntityMoniker.Name = "statecode";
from your code. This field Name has other purpose.
Also, you should add
setState.State.Value = 1;
setState.Status.Value = -1;
