Set up an Office 365 developer subscription
Set up an Office 365 developer subscription to build and test your solutions independent of your production environment. The subscription is an Office 365 Enterprise E3 Developer subscription with 25 user licenses. It lasts for one year and is free to use for development purposes (coding and testing solutions).
To set up a subscription, you must first join the Office 365 Developer Program. After joining, you'll see the option to set up a subscription.
Set up your subscription
To get an Office 365 developer subscription, on your profile page, under Need an Office 365 subscription to use for development?, choose Set up subscription.
In the Set up your developer subscription dialog box, create a username and domain. This account will have global administrator permissions for the subscription. You can choose any username or domain name as long as it is not already in use. Do not use spaces.
Create and confirm a password.
Choose Set up.
If you are asked to prove you're not a robot, follow the instructions, and then choose Verify.
After the subscription is created, your subscription name and expiration date appear on your profile page.
Make a note of your username and password because you'll need it to access your developer subscription.
Configure the subscription
On your profile page, choose the office.com link and sign in with your user ID (for example, firstname.lastname@example.org) and the password you specified for your developer subscription.
Do not sign in to your subscription with your developer program credentials.
Use the app launcher to go to the Admin center.
On the Admin center home page, choose Go to setup. This will take you to the Office 365 Enterprise E3 Developer Setup page.
Personalize your sign-in and email. You can connect your subscription to a domain, or just use the existing subdomain that you created. When ready, choose Next.
Add new users. You can add users. These could be fictional users that you need for testing, or real users helping you with development. When ready, choose Next.
If you need to bulk-add users, you can do this later. For more information, see Add users individually or in bulk to Office 365 - Admin Help.
Assign licenses to unlicensed users. For any users that you want to be able to work with the subscription, grant them a license. When ready, choose Next.
Share sign-in credentials. For any real users who will access the subscription, you must share their sign-in credentials with them. You can choose a method, such as email, download, or print. When ready, choose Next.
Install your Office apps. You have the option of installing Office apps to your computer. When ready, choose Next.
On subsequent visits to the Dashboard, sign in with your email@example.com account before you go to the Dashboard.
You've reached the end of setup. You've completed the setup for your subscription. You can optionally rate the experience. When ready, choose Go to the Admin center.
At this time, the subscription's region defaults to North America regardless of which country/region you are in. You can still proceed with setting up and using your developer subscription.
Provision Office 365 services
It will take some time for the backend services, such as SharePoint and Exchange, to provision for the subscription. During this step, some of the icons in the app launcher and on the Home page show as Setting up (This app is still being set up). This will take no longer than an hour.
When the provisioning is complete, you can use the new Office 365 subscription for development and testing. The subscription expires after one year.
We also recommend that you enable release options to ensure that you get access to the latest Office 365 features as soon as possible. For more information, see Set up the Standard or Targeted release options in Office 365.
Set up a Microsoft Azure account
For some Office solutions, you might need a Microsoft Azure account to build and test using Azure services. To set up a free Azure account, see Create your Azure free account today.
Leave the Developer Program
If you decide that you no longer want to participate in the Office 365 Developer Program, you can end your subscription and leave the program.
The following steps will erase all of your profile information. You will lose any data stored in your developer subscription that is not backed up elsewhere.
Sign in to the Developer Program.
Choose Delete Profile.
In the Delete Profile confirmation box, choose Delete.
