private ExchangeService connectToEWS(string email, bool impersonate = false) {
   WebCredentials credentials = new WebCredentials(username, password, domain);
   ExchangeVersion version = (ExchangeVersion)exchangeVersion;
   ExchangeService service = new ExchangeService(version) {
      Credentials = credentials,
      Url = new Uri("https://outlook.office365.com/ews/exchange.asmx")
   };
   if (impersonate) {
      service.HttpHeaders.Add("X-AnchorMailbox", email);
      service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, email);				         service.CookieContainer = new CookieContainer();
   }
   service.Timeout = int.MaxValue;
}

Using the code above as well as 

ExchangeService service = connectToEWS(email, true);
FolderId msgFolderRoot = WellKnownFolderName.MsgFolderRoot;
FolderView view = new FolderView(int.MaxValue);
view.PropertySet = PropertySet.IdOnly;
var result = service.FindFolders(msgFolderRoot, view);

I receive a 401 unauthorized exception on the FindFolders call. If I use the other constructor of WebCredentials that takes only the smtp and password, I get a 503 server not available exception. When I do not use impersonation (delegate access instead), no exceptions are thrown and I can get the list of folders however I need to be able to support impersonation.

I have added ApplicationImpersonation role to the service account (username in the first code block). Is there another role required for impersonation? I can not find anything in the EWS impersonation documentation. Every other thread about this issue points to the UPN usage rather than smtp but I am fairly sure this smtp is the same as the UPN. I don't actually know where to look within o365 however.

How to update appointment message body via EWS in powershell? I can find appointment through $service.FindAppointments but I can't get body message. Please help!

My code:

Import-Module "C:\Program Files (x86)\Microsoft\Exchange\Web Services\2.1\Microsoft.Exchange.WebServices.dll"

$service = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService([Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2007_SP1)

$creds = New-Object System.Net.NetworkCredential('login','pass')
$service.Credentials = $creds

}

And:
1. how to get body?
2. how to modify body and save changes in source appointment?

I asked this question in the Powershell subreddit today but am trying to get closer to people who specialize in this area. Please move if I didn't pick the appropriate forum.

Hi everyone,

I need to construct a VBSCRIPT that should be executed at Login time, and that send an email to external domain using the user mailbox. The user(s) doesn't have Outlook installed on his workstation, but OWA, and can't use the SMTP Server due relay restrictions. Also, I don't want the user insert his credentials again after login when the script executes, for don't compromise them. I've been trying to follow this article: https://msdn.microsoft.com/en-us/library/aa494235(v=exchg.80).aspx but it seems it was written for Exchange 2007. I have been using both DSQUERY and ADSI Edit tools for locating the mailbox URL but I haven't been able to get it. Could you please let me know how can I get the mailbox URL of an specific user in Exchange 2012, better using Active Directory, or how can I  get the User Credentials after login, in such a way they can be used for sending authenticated emails to outside?. 

Thank you in advance.

Good day.

I recently installed Microsoft Exchange 2016 over Windows Server 2012 R2.

IMAP4 , POP3 services are on.

I created an email account on Exchange and i tried to move my 5000 emails from local pst to the Exchange Account over IMAP.

(Windows 10 Professional x64, Microsoft Outlook 2013 x32 , one account local and a second account with IMAP to this Exchange Server.)

I copied the files from Inbox of my local account to IMAP account (copy function of outlook 2013). The target files appeared correctly to the IMAP view of Outlook Client, but the Microsoft Exchange Server 2016 stopped to synchronize the files, with the "Microsoft Exchange Notification Broker" Service stopped. I tried to restart the service and for some seconds, some emails synchronized and then the same service stopped. And this goes on all over again. This event make the transfer of 5000 emails impossible. Any ideas ???

Hi,

Pretty new to Exchange Development and I'm trying to install the transport agent from this blog: https://blogs.technet.microsoft.com/appssrv/2009/08/26/how-to-control-routing-from-your-own-routing-agent/ but not having any luck.

The error I get is:

The TransportAgentFactory type "RoutingAgentOverride.SampleRoutingAgentFactory" doesn't exist. The
TransportAgentFactory type must be the Microsoft .NET class type of the transport agent factory.
Parameter name: TransportAgentFactory
    + CategoryInfo          : InvalidArgument: (:) [Install-TransportAgent], ArgumentException
    + FullyQualifiedErrorId : [Server=QA-EXCH13-01,RequestId=86424b9f-edc1-4b6b-8450-a497b08c899c,TimeStamp=13/11/2016
    11:22:47] [FailureCategory=Cmdlet-ArgumentException] 2C8C2427,Microsoft.Exchange.Management.AgentTasks.InstallTra
  nsportAgent

The command I'm using is:

Install-TransportAgent -Name "RoutingAgent" -AssemblyPath "C:\RoutingAgentOverride.dll" -TransportAgentFactory "RoutingAgentOverride.SampleRoutingAgentFactory"

The top part of the code as per the blog:

namespace RoutingAgentOverride
{
    public class SampleRoutingAgentFactory : RoutingAgentFactory
        {
            public override RoutingAgent CreateAgent(SmtpServer server)
            {
                RoutingAgent myAgent = new ownRoutingAgent();
                return myAgent;
            }
        }

So I think I've got the command right and testing out the installation on a Exchange 2016 server it sucessfully installed, however on my Exchange 2013 CU14 server it does not.  I am using the same versions of the Microsoft.Exchange.Data.Transport.dll and Microsoft.Exchange.Data.Common.dll that come with Exchange 2013 CU14

I tried the fixit script in https://support.microsoft.com/en-us/kb/2938053 but that made no difference.

Is anybody able to suggest anything that I can do to get the transport agent installed on my Exchange 2013 box?

Will someone please chime in on what is up with this?

This is a server 2012 r2 std, exchange 2016 install... it is not a DC, (The DC is a 2016 std)...

The install gets to

Hello,

I'm building a transport agent for Exchange 2013 and I would like to use a configuration file for this agent.

I do not want to read the configuration file each time a TA is created in order to avoid the IO and time needed, is there a way to have it memory for all instances of the agent?

Thanks in advance,

Christos

Hello guys,

I got an important task from one of our customers:

He wants me to run through all public folders (I guess something like 60.000 or more / around 500 GB) in Exchange 2010 and remove the duplicate folders, mails, calendars and contacts.

As far as I know is there no official third party tool.

Can someone help me with a small script oder a few ideas to accomplish the task?

Thanks in advance,

Benjamin

Hi,

my question was forwarded into this forum.

I was thinking about the following: Is it possible to get the "out of office" status from an external platform (for example SharePoint Online). In the other forum there was EWS mentioned but I''m not sure if this works from client side (meaning things like SharePoint Designer or so..).

Maybe someone here has a good guess? :-) 

Best regards,

André

I write an exchange transport agent, and want to deploy for test. for security reason, i want let the agent just process emails that send or received by a part of users. 

e.g. my environment is Exchange 2013.  I have three Mailbox Servers.

MBS 1 (hosted user: user10, user11,user12)

MBS 2(hosted user: user20, user21, user22)

MBS 3(hosted user: user30, user31, user32)

i want let the agent just process emails that send or received by user10, user11, user12. so I just installed the transport agent in MBS 1.

but the result seems there are some email send or received by user10, user11, user12 that didn't processed by my agent.

is there a method to deploy Exchange Transport Agent to only affect a part of users ?

Hi,

We are planning to implement Outlook calendar  bi-directional sync for in one of out application using EWS SOAP services . It should sync appointments from outlook for thousands of users using batch job. Here is the approach we through of.

1. Using SyncFolderItem we would like to get calendar items in batches (25-50 per batch) for each user and call GetItem to retrieve Data.

Is it the correct approach?

I looked at Subscriptions functionality in bulk upload, looks like it will be best suited for individual user  sync and not for bulk users sync. did any one implement subscriptions for processing sync for thousands of accounts.

There are two ways to get changes from Exchange using EWS API:

1. Use SyncFolderItems to get a list of changed items
2. Use FindItem to get a list of changed items (filtered by modify time)

My use case is not the typical mobile sync email situation. I just want to quickly scan mailboxes and find new items since last scan (so I don't care about changed items, read status, deleted items, ..).

Since many mailboxes need to be scanned, performance is a major consideration. I thought that SyncFolderItems would be more efficient as it only works on 'changes'. However, from my testing with large mailboxes/folders (for example, 20000+ items in folders, with 200 new items each folder), it appears that the performance of SyncFolderItems and FindItem are the same. 

I'm inclined to use FindItem based on the testing result, as this approach is simpler and no need to maintain the Sync State information for SyncFolderItems. I'm wondering if Microsoft or someone can help to confirm this finding, or are there some other considerations? Thanks!
