EWS Managed API, Why Item.DateTimeSent.Millisecond is always zero?

December 6, 2018, 3:38 am
$

I am trying to calculate the time taken to send email message and time taken to receive email message. i am using EWS in my program , I set streaming notification to receive call back when a new mail reaches reciptent mailbox .

once received notification i bind the Itemevent with ews service , i checked the item properties DateTimeCreated, DateTimeSent, DateTimeReceived.All these properties are of DateTime object.

I checked DateTimeSent milisecond is always 0, whereas DateTimeCreated, DateTimeReceived has millisecond value.

I couldnot figure out why DateTimeSent millisecond is always 0 everytime. if i want to claulate time taken from send to receive what should i do.

DateTimeReceived - Datetimesent is the actual time taken to send and receive the message?

or what is the correct way to calculate time taken to send and receive the message?

The double-hop to Exchange (EWS) via web site (IIS 7) without setting browsers negotiate delegation list

December 7, 2018, 12:27 am

Hello,

i have an asp.net mvc 5 application hosted by iis 7 that allows to do basic CRUD operations with user's Exchange calendar items (meetings, appointments). All users are in domain. In IIS: win authorization - on; impersonation - on; useKernelMode - on; AppPool - ApplicationPoolIdentity.

Mostly done as written here https://stackoverflow.com/questions/41424890/ews-managed-api-double-hop

If i set up a browsers NegotiateDelegate white-list on the client machine, my site doesnt ask for login\pass and immediately log in. Everthing is good, default credential pass to Exchange (2016) so i can see (or create, update) my calendar's items on a web page.

If i doesnt set up browers for delegation, site asks domain login\pass, but Exchange returns "The request failed. The remote server returned an error: (401) Unauthorized."

In both cases (if the site asks or not a login), I obtain WindowsIdentity.GetCurrent().Name and other AD properties such as email, ExtensionAttribute.

My question: is it possible to pass default credentials without configuring browsers? Each browser is configured differently and it’s not good to customize them for each user individually. Or maybe I should use a different method than kerberos(NTLM)?

sry 4 my english.

[E2007SP1][EWSMA][C#] CalendarFolder.FindAppointments - Recurrence has no occurrences in the specified range.

Hello All.  I'm trying to retrieve all of the calendar items for a particular user and date range.  Here is a small code snippet:

        ExchangeService exchangeServiceObject = new ExchangeService(ExchangeVersion.Exchange2007_SP1);//Set the url for the service
        exchangeServiceObject.Url = new Uri(webServicePath);//Set the credentials for the service
        exchangeServiceObject.Credentials = new WebCredentials(userName, password, domain);//Try to bind to the logged on user's calendar folder (Users with mailboxes on Exchange 2003 will fail with ServiceXmlDeserializationException)
        CalendarFolder myCalendar = CalendarFolder.Bind(exchangeServiceObject, WellKnownFolderName.Calendar);//If the calendar is valid, query it using the supplied dates - Expanding all recurrences by using CalendarView if (myCalendar != null)
        {
          CalendarView calendarView = new CalendarView(startDate, endDate);
          FindItemsResults<Appointment> myAppointments = myCalendar.FindAppointments(calendarView);

This code seems to work for 99% percent of the users.  I have 1 user (so far) that receives the following error on the myCalendar.FindAppointments call:

"Recurrence has no occurrences in the specified range"

Does anyone have any idea why he's receiving this error?  We have tried several different date ranges, but it appears as though he receives this error regardless of the date range specified.

Thanks.

Private flag not changed on room reservation after change on Organizer's calendar

December 7, 2018, 7:24 am
$

Please advise if this is not the best forum since my scenario is on Office365.

If I create a new private meeting, and add a room location that is defined as a resource, the meeting on the room's calendar correctly reflects the private flag.

However, if I then edit the organizer's calendar and clear the private flag, the room's calendar does not appear to be updated with this change.  

I am querying the room's calendar via Graph API and the Sensitivity value remains Private.

We have set up the CalendarProcessing settings for the room for RemovePrivateProperty == false as required to allow the room to be marked as private if the incoming meeting request is private.  

Our workaround is to do 2 queries, first for the room, then a 2nd to get the organizer's meeting, but I'm trying to confirm that the background update to the rooms calendar skips over these fields.

Thanks in advance.


UPDATE: I can confirm that if the meeting begins as non-private, but then is marked as private, the room event DOES reflect this change.  So it appears to only be the scenario where the private flag is cleared.

Office 365 Mailbox programatic access fails: The Autodiscover service couldn't be located.

Not sure if this is the correct place but here goes:

I have been given a mailbox and I have written a windows service to look into the mailbox and process email messages.

The mailbox is of the form: createlead@api.mydomain.com

I log in to office365 with this email address and the password and I can see the mailbox just fine.

I try to connect with code:

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);

Service.Credentials = new WebCredentials(username, password); //username as quoted above.

I get the following error:

I have tried the Remote Connectivity Analyser but can't work out which option I should be choosing (Office 365 General Tests? Single Sign On?)

Tried this and got error: The domain  isn't a federated domain.

Not sure if this is saying I am using the wrong option in the Remote Connectivity Analyser or if there is something wrong with the mailbox.

Can anyone help?

I have been given write access to a shared calendar for a username/pwd that I use to authenticate programmatically to the Exchange server. I want to programmatically add an appointment to this shared calendar using EWS. But I don't see how through the api doc/wsdl. When I use the following I can add an event to the user's personal calendar that I am authenticating to in my code. I want to add the event to a specific shared calendar that this user has write privileges for. All the examples I see are in C#. I don't know C#.

OST to PST Software Coding

Hello Everyone,

I am currently looking at writing some software that would allow users to be able to create a PST from an OST, I am new to coding and would look to distribute this application for free with no limitations.

I know the task can be done but the software always has limits, however as admins we always need it in the event of a failure hence the above track. If anyone can point me in the right direction for information as what I have found online is fairly useless.

Thank you in advance

Hi,

We are trying to write a module (HttpModule) that will intercept the requests sends to the Exchange server over rpc-http or mapi-http. We put our module at the location Autodiscover, mapi, rpc in the Defualt Web Site. We do able to capture all the requests send to the Server. But what we want that only the request when the user authenticates with the user name and password in the Windows Security dialog, we process the request and ignore the rest. Especially in case of Mapi-Http we are continually getting request at the Module placed at the Default Web Site\mapi.

How to Merge pst file with exchange server using MAPI

hi,
    I have one pst file, i want  to merge all the mailboxes in PST file into exchange server using MAPI.
    I used PR_SEARCH_KEY to compare pst file mails with exchange server mails, so that we can copy messages which are not present in the exchange server mailbox. But  this approach fails to match search key, so not able to merge the mails.

   Is there any options available in MAPI to merge pst file with Exchange server mailboxes.
  
   Is PR_SEARCH_KEY unique in both pst mails and Exchange Server Mailbox mails?.
  
   If not , then any other unique key is available for every individual mails in Exchange Mailbox. Also tell information about merging with exchange server mailbox using any other approach.



  reply the answer as quick as possible,
  Thanks in advance.

DKIM signature and body hash validation issue

December 15, 2018, 7:10 am

I am working on a DKIM verification plugin (runs on EndOfData event) for Exchange Server (2010-2019), however Exchange keeps modifying the message header fields and certain elements of the message body which breaks the DKIM signature and body hash in the incoming emails. I have tested this on Exchange 2010-2019 servers (/w latest CUs & RUs) with various roles, but all version+role combination seem to do this. The strange thing, however, is that I could find find any KB or article on this.

Has anyone encountered this issue before? Is there a workaround or Exchange setting that I am not aware of?

Just a few examples:

- In case of multipart emails, the lines between the first boundary and the message header are removed.

- Certain header field values get wrapped with double-quotes.

- If there are more than 2 lines breaks between the header and body, they get reduced to 2.
