Getting Started with Office development: Common Questions

Let's say you've signed up for an Office 365 developer account. The following is what you get access to:

Q: Can I download Word, Excel, PowerPoint, Outlook, OneNote for free now?

A: Yes, click on the red "Install now". I'm not sure if your developer account allows you to use them for the duration of your developer trial, but I'm pretty sure they won't work after your 30-day trial expires anyway. This isn't a way to get Microsoft Office for free. The point of having those apps there for you to download is to show that for any Office 365 user, they get installations of the Office apps that comes with their Office 365 subscription that they either purchased themselves or that their company purchased for them.

Q: Why does my "OneDrive" or "Sites" icon remain grayed out even after a few minutes?

A: SharePoint is still provisioning. When you set up an Office 365 tenant (remember: a tenant looks like or, you are saying that I'm buying Office 365 for all the users belonging to my company which has a domain name of or Office 365 doesn't only include Word, Excel, PowerPoint etc., it also includes SharePoint (a powerful intranet/file management and collaboration solution) and Exchange (an email server that allows you to provide email services for your company). SharePoint and Exchange used to be sold as software in boxes, but now they are all online as part of the Office 365 cloud solution. The icons "Sites" and "OneDrive" represents SharePoint. In particular, it may take some time for SharePoint for your or company to set up so be patient.

Q: It still remains grayed out even after 1 hour!

A: SharePoint probably failed to provision. This is something that we are aware of and working on fixing. Please post your problem on the community forums (click on "?" in the top right hand corner) and someone will work with you to fix your specific problem.

Q: What is the difference between OneDrive here and

A: "OneDrive for Business" is distinct from "" and "OneDrive". The Pro/Business solution is essentially a file management solution from SharePoint that is a cloud storage solution for your company. is cloud storage for individuals. Let's say you are working on an important proposal for a meeting next week at work. That would probably go onto OneDrive Pro and not But if you want to store your own photos taken at your kids' birthday party, that would go onto In the context of Office 365 tenants and developer accounts, the word "OneDrive" refers to "OneDrive for Business". Outside the context of the enterprise, the word "OneDrive" refers to "" or OneDrive for consumer services.

It's confusing, I know. But I'm here to answer your questions - feel free to post them in the comments below.

Register for an Office developer account

There's lots of confusion over what you need to do before you can start developing on the Office platform so I'd like to clear it up here.

You need an Office 365 developer account. Sign up here for a 30 day free trial. It costs $99/year thereafter.

Note: If you are an MSDN subscriber (with Visual Studio Premium or Visual Studio Ultimate), you can get this developer account for FREE.

This post will show you a clear, step-by-step walkthrough of how to register for an Office 365 developer account.

First you enter your personal details:

Then you tell Microsoft what you want your tenant domain and username to be. Office 365 is aimed at enterprises, so imagine a situation where a company A has its own in house developer named B. So in this case, the tenant domain will be and theusername will be developerB. So developer B's login account to Office 365 will In this case because you are signing up for a free trial Microsoft doesn't have domains like to give away. You have to use but you can later associate this to your own domain.

The next step is a verification step:

Enter the verification code you receive:

Wait a few seconds while your account gets created:

Your account is created.

You will receive an email with your tenant domain and username. This is handy information in case you forget. Note that my user ID is - this is a completely different sort of account from a type of account. The former is an Office 365 tenant account where the latter is a Microsoft account. Think of the difference as the former being an enterprise log-in that you use at work, and the latter being your own personal account that you use for Bing,, and all of Microsoft's consumer services.

Now when you click on "Access your Office 365" in that email, or if you click on "You're ready to go..." in that registration screen, you get to this:

And there you have it! You've set up a developer account for Office 365.

If any of the "tile" icons representing Word Online, Excel Online, PowerPoint Online, OneDrive, Sites, Outlook, Calendar or People are grayed out, that means these services haven't finished provisioning yet. Give them a few more minutes, and when you refresh, they should be ready to use.

That's all you need to start using O365 APIs!
