I'm trying to use EWS to synchronize calendars between my SharePoint-based application and Exchange.

Reading through https://msdn.microsoft.com/en-us/library/office/dn440952%28v=exchg.150%29.aspx gives me conflicting information.

• Use an approach similar to notification-based synchronization. Because SyncFolderItem does not include any calendaring logic, use the EWS Managed API FindAppointments method, or the EWS FindItem operation with theCalendarView element to view appointments between two dates, and then call the EWS Managed APILoadPropertiesForItems method, or the EWS GetItem operation to retrieve the item properties for the calendar item.

• Do not poll using the EWS Managed API FindAppointments method, or the EWSFindItem operation with a CalendarView element.

These two points directly oppose each other. One says to use specific EWS methods, while the other says these methods shouldn't be used.

Also, even disregarding the conflict of those two points, there's no mention of how to actually sync calendar data. The biggest issue I have is that any modifications to recurring master items remove any recurrence exceptions (both in Exchange as well as in my SharePoint!). Because of this things tend to be a real mess.

Is there a clear-cut design pattern used for periodic synchronization of calendar events between Exchange and a client application?

Hi,

I'm using Exchange (Office 365) and I have a problem with appointments that have 'corrupted' StartTimeZone properties. When I request the appointment I get the following StartTimeZone property in the response:

As you can see the StartTimeZone Id as well as some other nested properties contain null characters. I'm trying to 'fix' this appointment by settings the StartTimeZone to UTC, but when I try to update the appointment I get the error: Set action is invalid for property.

How can it be that Exchange sends back an invalid StartTimeZone, and I'm unable to change it to a valid timezone?

BTW EWSEditor shows an empty value for StartTimeZone:

Hi

Can anyone point me in the direction of links that show how to use vb.net with MS Exchange?

I want to do things like put an appointment into a user's exchange appointments or send email to a user's exchange inbox.

i can't seem to find any helpful links.

Thanks

I am working on an ASP.NET MVC site that accesses our local Exchange 2013 server. Everything works fine on my development machine with VS 2013 + IIS Express and the db on SQL Express (on another machine).

The deployed application however throws 401.2 when accessing Exchange with the current user (SQL Server is running on the same server). This should be a problem with Kerberos delegation. Unfortunately I did not get it to work after hours of searching and configuring. So here's what I have:

• EWS Managed API V2.2
• Windows Authentication enabled in web.config and on IIS
• I use the same domain user when testing on my local machine and the webserver

IIS Configuration:

• Windows Authentication Providers: Negotiate, NTLM
• Windows Authentication Advanced Settings: Extended Protection Off, Kernel-Mode Auth DISABLED
• ASP.Net Impersonation activated on the productive webserver
• Application Pool runs as a domain user ("Contoso\roomplanner")
• "useAppPoolCredentials" in ApplicationHost.config for site = TRUE

AD configuration:

• AppPool user trusted for delegation, webserver trusted for delegation
• Added SPNs for Contoso\roomplanner: http/webserverNETBIOS; http/webserverFQDN

I followed this tutorial for Kerberos Delegation:http://blogs.msdn.com/b/chiranth/archive/2014/04/17/setting-up-kerberos-authentication-for-a-website-in-iis.aspx

Code I use to connect to Exchange:

publicvoidAuth(WebCredentials creds, bool useAutodiscover,string EWSURL =null){if(useAutodiscover){// not of interest, because I always use the EWSURL in this scenario}else{if(!String.IsNullOrEmpty(EWSURL)){
            service =newExchangeService(ExchangeVersion.Exchange2013_SP1);

            service.CookieContainer=newCookieContainer();

            service.TraceEnabled=true;

            service.Credentials= creds;// CURRENT USER in this case

            service.Url=newUri(EWSURL);}else{// ERROR}}}

Here is a sample of a following operation on the Exchange:

publicList<EmailAddress>GetAllRoomAddresses(){var roomlists = service.GetRoomLists();List<EmailAddress> roomAddresses =newList<EmailAddress>();foreach(var item in roomlists){
        roomAddresses.AddRange(service.GetRooms(newEmailAddress(item.Address)));}return roomAddresses;}

TL;DR: Everything works fine on my development machine. The Exchange Server however denies access, when accessing the site through a regular IIS (Double hop scenario).

Can somebody tell me how I get this to work?

Regards

Hello,

I Want to set permission as “None” for all the users on public folders which are inactive since last 180 days.

Please do let me know if you have any poweshell script for this purpose?

Hi,

I am wondering how people recommend implementing either an Exchange application (or anything simpler) that requires users to only have meetings during a certain time range (Either office hours or just a general time range). If someone tries to book outside the range, it auto sends a rejection email or something similar.

Ideally, it would be before the user even can see the meeting request but I could settle for best effort (Given it is reasonable).

I am thinking of using the EWS API or any other Exchange API if it will work. I'm wondering if this is realistic since I have no Exchange programming experience.

If so, how I would approach doing this?

i am trying to access a mailbox using EWS api.

i use a global admin with application impersonate role to access the mailbox, it failed and return an error "Unable to access an account or mailbox"。

use the global admin i can access all the mailboxes but this one. I am very confused, don't know what's special about this mailbox.

I assign the global admin full access rights to this mailbox, and try to use this via powershell or EWS api to access the mailbox, it falied again.

But i can access the mailbox using its own account

Anybody know why i cannot access this mailbox using other account. I am very sure that the code i used has no problem, because it works on other mailbox.

Hi All

I'm connecting to the Exchange Server 2010 SP2 from my C# application with EWS version 2.2 to download a big image attachment in my calendar item. The image size is 5,976,794 bytes as reported by fileAtt.Size property. The application throws exception:

Microsoft.Exchange.WebServices.Data.ServiceResponseException: The attachment could not be opened.
at
Microsoft.Exchange.WebServices.Data.ServiceResponse.InternalThrowIfNecessary()

at
Microsoft.Exchange.WebServices.Data.Attachment.InternalLoad(Nullable`1 bodyType, IENumerable`1 addtionalProperties)
at Microsoft.Exchange.WebServices.Data.Attachment.Load()

Here is my code to download the attachment:

service.LoadPropertiesForItems(items, PropertySet.FirstClassProperties);
foreach (Appointment a in appointments) {
	string htmlBody = a.Body.Text;	
	foreach(Attachment att in a.Attachments) {
		if (att is FileAttachment) {
			FileAttachment fileAtt = att as FileAttachment;	
			FileStream theStream = new FileStream(String.Format(@"ANP\{0}", att.ContentId ), FileMode.OpenOrCreate, FileAccess.ReadWrite);
			fileAtt.Load(theStream);
       theStream.Close();
       theStream.Dispose();
		}
	}
}

The exception is triggered by this code line: fileAtt.Load(theStream);

Do I miss something ? If the attachment is < 5 Mb, the codes run very well and I can download the attachment.

Please help.

Thank you so much.

Hi,

I try to add users and groups to the delegates via the EWS API. There is no problem with user but I can not add groups. How can I add groups via the EWS? Thank you for your help.

Exchange 2013 SP1 with 2 member DAG with 1 DB. I want to monitor the DAG using collectovermetrics.ps1. I want to have the html report from collectovermetrics.ps1 email to administrators. I know I have to have task scheduler run the command:

CollectOverMetrics.ps1 -DatabaseAvailabilityGroup DAG1 -StartTime "06/15/2012" -EndTime "06/16/2012" -GenerateHTMLReport –ShowHTMLReport

But how do I have that report emailed? I know you can use:

Send-MailMessage -To user@user.com -From user2@user.com -subject "This is a test" -Credential (Get-Credential)

But this fails with:

send-mailmessage : The email cannot be sent because no SMTP server was specified. You must specify an SMTP s
using either the SmtpServer parameter or the $PSEmailServer variable.
At line:1 char:1+ send-mailmessage -to user@domian.tld -from user2@domain.tld+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : InvalidArgument: (:) [Send-MailMessage], InvalidOperationException+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.SendMailMessage

Can anyone help with this?

We have an application that should connect to Office365 mailboxes and update calendar entries for selected users.   The connection tests successfully but when an attempt is made to update a specific mailbox, we receive the following in our trace:

Exception: System.Net.WebException

We have confirmed that the user mailbox does exist on the server and the error occurs regardless of the user being updated so we assume that this is related to the connection itself.  Other forum postings indicate that 403 can result when SSL connections are not used but we cannot find a way to confirm this is the cause in this case.  Any guidance you can provide to help debug this issue would be greatly appreciated.

I develop an Office Mail App which is used in Exchange 2013 On-Premises in my test lab. The mail app is hosted on IIS 8 (Windows Server 2012 R2) in the same LAN and ActiveDirectory domain.

Opening popup windows from the mail app does only work in IE, not in Chrome and Firefox.

Here are the details:

The following server and domain names are changed to hide our internal names. I adjusted the error messages accordingly.

Exchange 2013 is available at https://e13.some.dom/owa...
The app content comes from https://server.some.dom/...
Both the app and exchange server have valid SSL certicates.
Both server URLs are listed in the popup exception lists of the browsers I use.

The app generates html with an element which uses onclick to open another item in the same mailbox in a new browser window. Like so:
<a onclick="window.open('https://e13.some.dom/owa/#viewmodel=ReadMessageItem&ItemID=SomeValidID', '_blank', 'width=600,height=400');">click me</a>

Clicking that link in Internet Explorer (11.0.9600.17105; Update Versions: 11.0.7) opens a new browser window and shows the message specified with "SomeValidID". All good.

When I use Chrome (Version 34.0.1847.131 m) the popup browser window opens. I see some progress text "Starting..." and "Almost there..." and then this error:

:-(
something went wrong

In Firefox I see the popOutManager-access with "permission denied", but the popup window itself was already opened.
Seems like the opened popup window tries to open another window?

Any ideas how I get the popups from my mail app working in Chrome and Firefox as well?

Hello,

I've configured an application to use a specific service account to access my users' mailboxes. I've created and associated a throttling policy with this service account (no limit, null values).

In reviewing the event logs, I come across an error that seems to suggest the unlimited throttling policy is not being honored.

Microsoft.Exchange.Data.Directory.SystemConfiguration.OverBudgetException: This operation exceeds the throttling budget for policy part 'CAS', budget type: 'EWS'. Suggested backoff time 27227 ms. at Microsoft.Exchange.Data.Directory.Budget.CheckOverBudget(CostType costType) at Microsoft.Exchange.Services.Core.PushSubscription.BuildNotification()

Does anyone know what (specifically) 'policy part 'CAS', budget type: 'EWS'.' is referring to? 

Thanks

I am currently working on a Custom routing agent. We are rerouting emails based on a header values etc.

When rerouting messages we are using domains and RoutingDomain, RoutingOverrideclasses. At the end, we are calling SetRoutingOverride method.

I have to filter out certain messages and reroute them to a specific IP address, but I am not sure how to implement this.

Is there an API for rerouting to IP addresses or should I try to resolve IP with the dns resolve and then use that domain with the existing API ?

Hello, 

I have an EWS client built in JAVA which calls the GetUserAvailability and CreateItem operations. SOAP requests are sent over HTTPS. A service account is supplied which satisfies authentication challenges.

The client was built against Exchange Server 2007. Now the infrastructure is moving to Exchange 2013. Initially testing has surfaced an issue connecting and fetching FREEBUSY data from Exchange 2013. 

Exchange 2013 returns a 400 exception when I attempt to fetch FREEBUSY data for an existing mailbox. The same client returns data when pointed against the 2007 server. 

Can someone advise if the SOAP request for Exchange 2013 requires some additional header information ( compared to 2007 request)? 

Including a copy of the request i send incase someone sees something which i should change
