Overview

The Office 365 Starter Project sample uses the Office 365 API Tools client libraries to illustrate basic operations against the Files, Calendar and Contacts service endpoints in Office 365. The sample also demonstrates how to authenticate against multiple Office 365 services in a single app experience, and retrieve user information from the Users and Groups service. We'll be adding examples of how to use more APIs such as Email when we update this project, so make sure to check back.

Below are the operations that you can perform with this sample:

Calendar

• Get calendar events
• Create events
• Update events
• Delete events

Contacts

• Get contacts
• Create contacts
• Update contacts
• Delete contacts
• Change contact photo

My Files

• Get files and folders
• Create text files
• Delete files or folders
• Read text file contents (OneDrive)
• Update text file contents
• Download files
• Upload files

Users and Groups

• Get display name
• Get job title
• Get profile picture
• Get user ID
• Check signed in/out state

Mail

• Get mail (with paged results)
• Send mail
• Delete mail

Change History

January 26, 2015:

• Added mail capabilities.

December 17, 2014:

• Simplified authentication flow and client creation in AuthenticationHelper.cs file.

• Added cache for the information from the discovery service so that the app doesn't query the service more than once.

• Added support for corporate intranets and company accounts. The UseCorporateNetwork property of the AuthenticationContext object is now set to true. The project also now includes declarations for the Enterprise Authentication, Private Networks, and Shared User Certificates capabilities. See App capability declarations (Windows Runtime apps) for more information.

Prerequisites and Configuration

This sample requires the following:

• Windows 8.1.
• Visual Studio 2013 with Update 4.
• Office 365 API Tools version 1.4.50428.2.
• An Office 365 developer site.
• To use the Files part of this project, OneDrive for Business must be setup on your tenant, which happens the first time you sign-on to OneDrive for Business via the web browser.

Note: This sample will work if you are using Visual Studio 2015 with Update 1. After you configure the sample, though, you'll need to edit this key/value pair in your App.xaml file:

<x:String x:Key="ida:ClientId">your client id</x:String>.

The code in the sample looks for the ClientID key, so the key/value pair should look like this:

<x:String x:Key="ida:ClientID">your client id</x:String>.

###Configure the sample

Follow these steps to configure the sample.

1. Open the O365-APIs-Start-Windows.sln file using Visual Studio 2013.
2. Build the solution. The NuGet Package Restore feature will load the assemblies listed in the packages.config file. You should do this before adding connected services in the following steps so that you don't get older versions of some assemblies.
3. Register and configure the app to consume Office 365 services (detailed below).

###Register app to consume Office 365 APIs

You can do this via the Office 365 API Tools for Visual Studio (which automates the registration process). Be sure to download and install the Office 365 API tools from the Visual Studio Gallery.

1. In the Solution Explorer window, choose Office365Starter project -> Add -> Connected Service.

2. A Services Manager dialog box will appear. Choose Office 365 and Register your app.

3. On the sign-in dialog box, enter the username and password for your Office 365 tenant. We recommend that you use your Office 365 Developer Site. Often, this user name will follow the pattern @.onmicrosoft.com. If you do not have a developer site, you can get a free Developer Site as part of your MSDN Benefits or sign up for a free trial. Be aware that the user must be an Tenant Admin user—but for tenants created as part of an Office 365 Developer Site, this is likely to be the case already. Also developer accounts are usually limited to one sign-in.

4. After you're signed in, you will see a list of all the services. Initially, no permissions will be selected, as the app is not registered to consume any services yet.

5. To register for the services used in this sample, choose the following permissions:
   - (Calendar) – Read and write to your calendars.
   - (Contacts) - Read and write to your contacts. - (My Files) – Read and write your files. - (Users and Groups) – Sign you in and read your profile.
   - (Users and Groups) – Access your organization's directory. - (Mail) - Read and write to your mail. - (Mail) - Send mail as you.

6. Click OK in the Services Manager dialog box.

Note: If you see any errors while installing packages during step 6, for example, Unable to find "Microsoft.Azure.ActiveDirectory.GraphClient", make sure the local path where you placed the solution is not too long/deep. Moving the solution closer to the root of your drive resolves this issue. We'll also work on shortening the folder names in a future update.

Build

After you've loaded the solution in Visual Studio, press F5 to build and debug. Run the solution and sign in with your organizational account to Office 365.

Known issues

• None at the moment, but do let us know if you find any. We're listening.

Troubleshooting

• You receive an "insufficient privileges" exception when you connect to Office 365 as a normal user, i.e., someone that does not have elevated privileges and is not a global administrator. Make sure you have set the Access your organization's directory permission when you add the connected services.

• You receive errors during package installation, for example, Unable to find "Microsoft.Azure.ActiveDirectory.GraphClient". Make sure the local path where you placed the solution is not too long/deep. Moving the solution closer to the root of your drive resolves this issue. We'll also work on shortening the folder names in a future update.

• You may run into an authentication error after deploying and running if apps do not have the ability to access account information in the Windows Privacy Settings menu. Set Let my apps access my name, picture, and other account info to On. This setting can be reset by a Windows Update.

• You run the Windows App Certification Kit against the installed app, and the app fails the supported APIs test. This likely happened because the Visual Studio tools installed older versions of some assemblies. Check the entries for Microsoft.Azure.ActiveDirectory.GraphClient and the Microsoft.OData assemblies in your project's packages.config file. Make sure that the version numbers for those assemblies match the version numbers in this repo's version of packages.config. When you rebuild and reinstall the solution with the updated assemblies, the app should pass the supported APIs test.
