Office 365 Developer Account comes with only one licensed user.

How can we develop Exchange or Lync applications with one user? I cannot test chat or email with just myself. Provisioning 2 or 3 test users wouldn't hurt Microsoft, and we would be able to develop and test our applications. 
For me it is really complicated to ask my employer to pay for another Office 365 site, and all that because of the single user limitation. And what is the next step anyway? I need 2 or 3, max 5 users for development. Can I add just one or two licenses to my Dev site?

Thanks,

I'm having trouble getting OAuth credentials to work with EWS in Office 365.  At a high level I'm writing a SharePoint 2013 app and I'm trying to access the user's mailbox data in Exchange.  I did verify my EWS code is 'correct' by swapping out the OAuth code for a hard coded username and password and it worked perfectly.

I get a token back using the code below, however I'm getting a 401 when I try to get the access the user's inbox.  I left it off for brevity, but I am passing the token into a new OAuthCredentials object before accessing the inbox.

            string acsUrl = "https://accounts.accesscontrol.windows.net/";
            using (WebClient exchangeTokenClient = new WebClient())
            {
                exchangeTokenClient.BaseAddress = acsUrl;

                NameValueCollection requestParams = new NameValueCollection();
                requestParams.Add("grant_type", "client_credentials");
                requestParams.Add("client_id", "<clientid>@<realm>");
                requestParams.Add("client_secret", "<client secret>");
                requestParams.Add("resource", "00000002-0000-0ff1-ce00-000000000000/outlook.office365.com@<realm>");
                exchangeTokenClient.Headers.Add("Authorization", "Bearer " + ((SharePointAcsContext)spContext).UserAccessTokenForSPAppWeb);

                byte[] responseBytes = exchangeTokenClient.UploadValues("<realm>/tokens/OAuth/2", "POST", requestParams);

                string response = Encoding.UTF8.GetString(responseBytes);
            }

Has anyone actually done this?  I feel like it should be possible, but I can't seem to find a lot of documentation on the process.

Thanks

Hello,

I have a problem with ExchangeServiceBinding.CreateAttachment(...) method (EWS with Office 365)

• When I try to add a small attachment (e.g. 5 MB), then the method works fine.

The  box    Windows Server 2008 SP2 64 bit      Exchange Server 2007 SP1

I'm trying to enable TLS 1.1 and 1.2 on my Exchange server as well as the ciphers, but I have been unable to do so yet.   I have followed an example I saw and it didn't work

http://www.derekseaman.com/2010/06/enable-tls-12-aes-256-and-sha-256-in.html 

When I connect to my Exchange OWA page, its using TLS 1.0 and TLS_RSA_WITH_AES_256_CBC_SHA.  If I run a tester it shows that my server only supports TLS 1.0 and no other protocols.  I'm not sure where I'm going wrong on this. 

Thanks,

I have an environment which contains Exchange 2010 mailbox server and Exchange 2013 backend server. From Exchange 2013 Management Shell, I run "New-MailboxSearch" cmdlet , and specify ONLY 2013 mailbox in '-SourceMailboxes' parameter, NO 2010 mailbox. After several hours, I check this search status by run "Get-MailboxSearch", it always be "queued". No matter how long time past, it status won't change. So I have to stop and remove this search.

And I tried eDiscovery in 2013 ECP, it comes the same result, task status is "queue" forever.

But in another environment which contain only Exchange 2013 server, "New-MailboxSearch" runs very well.

Can I search 2013 mailbox in 2010 and 2013 hybrid environment?

Hello,

While moving mailbox from exchange server 2003 to exchange server 2010, i'm facing this issue. At the same time I ran the command in EMS for other mailbox it's completed successfully.

For the below error I checked the user in AD and given Mailbox full permissions in 2003 server(Given Full permission to service account which I used for migration). Again also same issue.

Can someone help me at the earliest.

I’ve been searching for hours for an answer to this problem but can’t find anything. I’ve seen posts that describe a similar problem but I’ve not seen any replies with an answer.

I’m writing an app that uses EWS Managed API to process emails arriving in mailboxes on an exchange server. It uses a single account with full permissions set to connect to each mailbox so it can process messages. It works fine when I read message content, open attachments, move messages, delete messages & create folders in the mailbox but I can’t get it to update a message.

If I call the “update” method on a message I get this exception:
When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids.

I can’t find any documentation on how I’m supposed to do this update.

Here’s some sample code:

ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate)

m_Service = New ExchangeService(ExchangeVersion.Exchange2007_SP1)

m_Service.Credentials = New WebCredentials("serviceaccount", "servicepassword", "mydomain")

m_Service.AutodiscoverUrl("test@mydomain.com")Dim MyMailBox AsNew Mailbox("test@mydomain.com")Dim InboxFolderID AsNew FolderId(WellKnownFolderName.Inbox, MyMailBox)Dim MessageList As FindItemsResults(Of Item) = m_Service.FindItems(InboxFolderID, New ItemView(1))Dim msg As Item = MessageList.Items(0)Try

 msg.Subject = "My test at "& Now.ToShortTimeString

 msg.Update(ConflictResolutionMode.AutoResolve)

Catch ex As Exception

 Debug.Print(ex.Message)

EndTry

If I run this code using the credentials of the mailbox I am working in it updates OK. If I run it using a different account that has full permission it throws the exception.

We have 2 Exchange 2007 SP3 CCR (2 Node). When i am trying to restore the database of CCR1 to RSG Created on CCR2 for the same storage group getting the below error message on Exchange server.

Hi,

I've been in touch with MS Support but haven't got anywhere, so I thought I'd try a wider knowledge base.

I'm trying to configure a hybrid between Exchange Online and Exchange 2010. I've configured on premise servers but am failing when trying to create the migration endpoint in Exchange Online. Autodiscover and OWA are working correctly both internally and externally. When I try to access either https://internalurl/EWS/Exchange.asmx or the external version I'm getting 401 error.

I have compared the output from "get-webservicesvirtualdirectory |fl" with my working test lab and it all looks okay, including Authentication Methods Ntlm, WindowsIntegrated, WSSecurity.

I have noticed that in IIS > EWS > Authentication that Forms Authentication is enabled which it isn't on my test lab. If I disable this I get Resource cannot not be found 404 error.

For the Migration Endpoint, I'm getting error MRSProxy cannot be found on the server. But this is True on the "get-webservicesvirtualdirectory |fl" command.

Thanks,

Chris

Hi,

I need to use Exchange managed api to send a plain text email, for which I'm using the following code:

_emailitem.Body = new MessageBody(BodyType.Text, somePlainText);

I thought this was working fine, but sometimes the text in someText might contain XML tags. E.g. The plain text needs to be:

"Hello world<END>FLAG</END>"

(This is because the email is getting sent to a special service and that service requires that the email is plaintext, but uses certain XML tags for special purposes).

Unfortunately, EWS appears to be stripping the tags! How can I send a simple plaintext email via EWS with the exact text I give it without EWS mangling the text?

appointment.save(), but not able to get recurring information of the event created in OWA interface, I get following error during the bind:

============================

This happens if I use: Appointment.bindToRecurringMaster or Item.bind(service, id, appointmentProps) or findAppointments(). 

Works fine for events which doesn't have recurring. Only issue with events containing recurrence created through OWA. These are the propertySet:

new PropertySet(BasePropertySet.IdOnly,

                                ItemSchema.Subject,

                                AppointmentSchema.AppointmentType,

                                AppointmentSchema.DeletedOccurrences,

                                AppointmentSchema.FirstOccurrence,

                                AppointmentSchema.LastOccurrence,

                                AppointmentSchema.IsRecurring,

                                AppointmentSchema.Location,

                                AppointmentSchema.ModifiedOccurrences,

                                AppointmentSchema.OriginalStart,

                                AppointmentSchema.Recurrence,

                                AppointmentSchema.Start,

                                AppointmentSchema.End);

If I remove Recurrence it gives the response. 

Thanks.

Hello,

Can you delete any custom extended properties without knowing their ID?

I took over managing a feature that used EWS to send emails to customers.The current code creates a new GUID, and thus new Extended Property, every time an email is sent.

// Create a custom extended property and add it to the message. 
var myExtendedPropertyDefinition = new ExtendedPropertyDefinition(Guid.NewGuid(), "MyGuidId", MapiPropertyType.String);

mail.SetExtendedProperty(myExtendedPropertyDefinition, "MyGuidId"); 

// Send and save a copy
mail.SendAndSaveCopy();

Thank you

Hello,

Exchange Version: Version 14.2 (Build 247.5)

I am using EWS Managed API 2.1 within Powershell.

Cached Exchange mode is on by default.

I have been attempting to delete the hidden delegate forwarding rule using EWS and been unsuccessful so far. I am using code that has at least worked for some people out there but I am unsure why it is not working for me. Every other command works for me no problem, such as getting information or adding/removing delegates (even deleting the ghost delegate information in the FreeBusy Information Message).

I have verified that I have FullAccess to the mailbox via Get-MailboxPermission and I have also attempted to give myself Owner on the Inbox in case that permission was also needed. I have tried using impersonation and also using access without impersonation and neither work. I am able to right-click and delete this object in MFCMapi though.

The Powershell error I get is the following:

Exception calling "Delete" with "1" argument(s): "Object cannot be deleted."

The EWS trace error I get is:

Now We are looking for High Availability in terms of database copy on local another server or how to activate them on in case if we freshly install exchange 2007 mailbox in chennai datacenter.

Please provide BEST Solution on this.
