I want to be able to use Exchange Web Services in order to create an instance of a custom Outlook form that has been previously created/designed and stored either in the Organizational Forms Library or just locally in the account's Personal Form Library.

Do the Exchange Web Services support creating items from custom templates or is it limited to just creating standard items (ie MailMessage, Task, etc)?  If so, is there any documentation available?

Hello,

I'm currently working on integrating an existing application with Exchange 2010 SP2 with the EWS Java API. I'm working on some design implementations and I find that I don't have the numbers to go one way or the other.

Basically, the current system schedules meetings. We're integrating it with Exchange to allow users to do scheduling and some management (not all, though) via Outlook. When a meeting is created in the current application and saved to its database, we also create an Appointment in Exchange. This is done via a single, dedicated account as that was the best fit for our system.

However, the design issue I'm seeing comes in from a scenario like this: User creates a meeting in the application. Appointment is created in Exchange and invitations are sent from the master account. The user later goes in to the application and makes a few changes, maybe the subject, body, time, or any other property we're saving to the Exchange Appointment. This requires us to update both the meeting in our application and the Appointment in Exchange.

The issue comes from the need to link the id for the meeting in the application to the id for the Appointment in Exchange (recurring meetings are not utilized, so that's not an issue). I'm torn between using extended properties for a few bits of info from the application (all Appointments will have the same set of extended properties definitions, but the id value will be unique) vs a database table to link the two ids and any other relevant information.

I'd certainly like to use the extended property as it won't require additional tables, etc on this end, but I've heard words of warning regarding the search for unindexed properties within Exchange. I can't accurately gauge the performance impact as I'm running this against a dev setup that is not very close to the actual server in terms of performance or the amount of data that Exchange needs to juggle.

I don't anticipate the update (or delete) option being utilized terribly often, but there will be potentially hundreds of meetings and even more responses going through this master account every day. We'll likely set up some cleanup operations to keep the inbox/calendar from overflowing, but I'm a bit concerned about the performance impact of searching by the value of an extended property. Can anyone shed some light on this?

Hello,

       i made a serious mistake,i set a transport rule that delete messages&no inform anyone, my question is how can i get these mails back ,and send &receive again for user,thank you.

Because of retention policies, we were forced to archive old email messages using the EWS API to EML files on the local system.  I am now trying to programmatically recreate some of these messages from the EML files.  I can open the EML files in Outlook and the message appears as normal (with expected Office Excel attachments).  Using the following code, I continually get Exceptions when invoking the EmailMessage.Save() method.  Very little info about what this is in the API docs.  Is it that the EML files are not true MIME?  Any help would be greatly appreciated:

	// load data from file
	byte[] content;
	using (var file = File.OpenRead(emailFile))
	{
		content = new byte[file.Length];
		file.Position = 0;
		file.Read(content, 0, (int)file.Length);
	}

	var message = new EmailMessage(service);
	message.MimeContent = new MimeContent("us-ascii", content);
	message.Save(WellKnownFolderName.Drafts);

Exception on Save() method:

Original Code to write the EML file:

// Finally, write an Outlook msg format, saved as .eml
message.Load(new PropertySet(ItemSchema.MimeContent));

MimeContent mc = message.MimeContent;
var fs = new FileStream(emlpath + "original.eml", FileMode.Create);

if (mc.Content != null) fs.Write(mc.Content, 0, mc.Content.Length);
fs.Close();

Hi All,

Client Access Role is a must in  every Exchange organization and every Active Directory site that has the Mailbox server role installed as mentioned here

My question is related to CAS and remote powershell.

To create a remote session, we make use of
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://Exchange_Server_Name/PowerShell/ -Authentication Kerberos -Credential $cred

Here for Exchange_Server_Name, we should provide the server name which has CAS role right ?

Also, if CAS role is not installed in an exchange organization, what would happen ? (I agree MS says we need to install).

I mean, can I provide server name which mailbox server role installed ?

Is the above valid ?

Hi,

I am using Exchange EWS to search mailbox for messages that match a certain search criteria. The examples are helpful, but I was looking for an example that allows you to search multiple folders using a single call. Is this possible?

http://msdn.microsoft.com/en-us/library/exchange/hh148195(v=exchg.140).aspx

contains

ItemView iv = new ItemView(1000);
SearchFilter sfSearchFilter = new SearchFilter.ContainsSubstring(EmailMessageSchema.Subject, "rugby");
FindItemsResults<Item> fiitems = service.FindItems(WellKnownFolderName.Inbox, sfSearchFilter, iv);

Note the above example only searches Inbox.

Since some users move items from Inbox to other folders, how can we be sure that those folders can be searches as well?

I am also aware of service.findFolders() to enumerate all folders. In some cases, this enumeration gives a large number of folders (some that do not have any new messages). However, I would like to limit the search to only the folders that have messages in the last six months.

Thanks.

To start off I have spent the last two hours looking through the older posts to find the answer to this one, so I apologize if I've overlooked it.

I developed a Middleware Web Service that our ticketing system can call to put appointments on our Live@EDU (Exchange Online) calendars.  I developed this in Visual Studio 2010 on Windows 7 behind a proxy service.  It worked great on that platform when I deployed it to the localhost.

I've now since deployed it on our development application server (Windows 2008 R2, IIS 7) which is also running through the same proxy service, and I'm getting this error when running my web service method:

Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException: The Autodiscover service couldn't be located.
   at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings[TSettings](String emailAddress, List`1 redirectionEmailAddresses, Int32& currentHop)
   at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.GetLegacyUserSettings[TSettings](String emailAddress)
   at Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverService.InternalGetLegacyUserSettings(String emailAddress, List`1 requestedSettings)

   at Microsoft.Exchange.WebServices.Data.ExchangeService.AutodiscoverUrl(String emailAddress, AutodiscoverRedirectionUrlValidationCallback validateRedirectionUrlCallback)

I can run the test for Web Services on 'http://testexchangeconnectivity.com' without a problem.  Any idea what might be occurring?  This server is a lot more locked down than my desktop where I developed it initially, and I have a feeling it's firewall (local or edge) related, but I'm not sure.

My next step is to run a WireShark trace and see what is happening, but I was hoping someone else might have run into this situation before as well.

Since I have installed the CU1 to the Exchange 2013 I get an Internal Server Error with the Managed Exchange API 2.0 if i try to use the SyncFolderItems function against a public folder.

I know, this was working with exact the same code before I have installed the CU1.

The problem comes up only if I have more than 6 items in the folder. I have tested with a contact and mailfolder. We can see the problem also on one of my customers Exchange Servers, he has also the CU1.

See this code to reproduce the error (Exchange "2" with a really existing public folder ):

The code will run trough all public Exchange folders and if it finds a folder named "2" it will use the function SyncFolderItems against that folder, the code is not sencefull but it will show the error if you have more then 6 items in it.

Import-Module -Name "C:\Program Files (x86)\Microsoft\Exchange\Web Services\2.0\Microsoft.Exchange.WebServices.dll"
$ews = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService -ArgumentList "Exchange2013"
$cred = (Get-Credential).GetNetworkCredential()
function EnumFolders($folderidcnt)
{  
   $fiResult = $ews.FindFolders($folderidcnt,$null,$fvFolderView)  
	foreach($ffFolder in $fiResult.Folders)
	{

		{"Found:"+$ffFolder.DisplayName"ID:"+$ffFolder.Id
			   $changes = $ews.SyncFolderItems($ffFolder.Id,[Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties,$null,512,[Microsoft.Exchange.WebServices.Data.SyncFolderItemsScope]::NormalItems,"")"Changes In Folder:" + $changes.Count
			   foreach($change in $changes)
			   {"-"+$change.Item.Subject
			   }
		}"- Folder:"+ $ffFolder.DisplayName;
		EnumFolders($ffFolder.Id);
	}
}

$ews.Url= "https://srv2012/EWS/Exchange.asmx"

$psPropertySet = new-object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties)  
$fvFolderView.PropertySet = $psPropertySet;  
$fiResult = $null  
do {  
    EnumFolders($folderidcnt);
}while($fiResult.MoreAvailable -eq $true)  

I have activated the tracelog in IIS. Here is some output from it.

Hello

I'm trying to deploy my exchange addin for MS Exchange 2010.

My dll must be built on .net 4.0 because it use an reference dll was built on .net 4.0.

When I try to install, it raise error "this assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded ...". I know exchange 2010 run on .net 3.5. 

I searched and some topic told that I install .net 4.0 and reset iis. I do it, but the problem raise the same.

So how can I deploy it ?

Hi,

I am building what will be a Windows service application using the EWS Streaming Notifications capability available in Exchange 2010 SP1.  I started with the example application discussed in the MSDN article entitled 'Using Streaming Notifications with Exchange 2010'.

I am only interested in new mail events in a single inbox. I have the OnNotificationEvent trigger successfully processing new mail events. I also have a background thread running that does a SyncFolderItems every 10 minutes. I am not exactly clear how the synchronization plays in all this, but the desire is guaranteed one-time processing of all new mail events. Therefore I am hoping the synchronization will provide “recovery” of events in case the service or other dependent resources are temporarily down.

My sync code is as follows:

  PublicSub SynchronizeChanges(folderIdAsFolderId)

       Dim moreChangesAvailableAsBoolean

       Do

           LogWriter.WriteLine("Synchronizing changes...")

           ' Get all changes since the last call. The synchronization cookie is stored in the _SynchronizationState field.

           ' Only the the ids are requested. Additional properties should be fetched via GetItem calls.

           Dim changes = _ExchangeService.SyncFolderItems(folderId,PropertySet.IdOnly,Nothing, 512,SyncFolderItemsScope.NormalItems, _SynchronizationState)

           ' Update the synchronization cookie

           _SynchronizationState = changes.SyncState

           WriteServiceSynchronizationState(_SynchronizationState)

           ' Process all changes

           'For Each itemChange In changes

           ' This example just prints the ChangeType and ItemId to the console

           ' LOB application would apply business rules to each item.

           'LogWriter.WriteLine("ChangeType = " & itemChange.ChangeType)

           'LogWriter.WriteLine("ChangeType = " & itemChange.ItemId.ToString)

           'Next

           ' If more changes are available, issue additional SyncFolderItems requests.

           moreChangesAvailable = changes.MoreChangesAvailable

       LoopWhile moreChangesAvailable

   EndSub

My question is about the commented out code at the bottom of the above sub. If the service or Exchange were unavailable for a period of time, is the For Each loop required to process new mail because the OnNotificationEvent would not have fired? If yes, then I will obviously need to adjust the For Each loop to suit my needs.

Also interested in feedback about whether or not this is a design that should provide guaranteed one-time processing of incoming mail. I do not expect this inbox to get much traffic but processing and responding is important.

I am writing some VB code to create contacts in public folders.  I am mostly finished.  However my created contacts come up as "Untitled" in the title bar.  I have set the "DisplayName" and "FileAs" properties as shown below.  However it doesn't change the title shown in the title bar.  I expect this has something to do with extended properties.  However I can't find a lot of documentation abou it.  Any help would be greatly appreciated.  Many thanks.

contact.GivenName = strGivenName
contact.Surname = strSurname
contact.FileAsMapping = FileAsMapping.SurnameCommaGivenName
contact.CompanyName = strCompanyName
contact.DisplayName = strGivenName & " " & strSurname
contact.FileAs = strGivenName & " " & strSurname
