Amazon Chime and Corporate Domain Names: Linking

Amazon Chime, a new unified communications service, runs entirely on Amazon Web Services (AWS). Amazon recently allowed AWS subscribers to associate their corporate domain with their Chime account.
This is advantageous because any user who signs up using an email address that is based upon your domain name will automatically be added to your Chime account.
Log in to your AWS account to access the list of services. Enter Chime in the AWS Services search field. This will take to the AWS Chime Accounts homescreen, which can be seen in Figure 1.

This pop-up warns that anyone can see your account name. It is important to avoid including any sensitive information in the name. Enter a name for your account and click the Create Account button. As shown in Figure 2, your new account name will appear on the Accounts screen.

AWS will automatically create a Chime team accounts. A team account is basically a workgroup account. Although team accounts are easy to manage, if you want to associate your corporate domain with Chime, an enterprise account is better.
There is a way to convert your team account into an enterprise account. Simply associating your corporate domain with the account will convert it into an enterprise account.
Click on the account you have just created to get started. You will be taken to the Summary screen shown in Figure 3. The Summary screen confirms account type and account name, as you can see in the figure.
[Click on the image to see a larger view.] Figure 3: A summary screen opens when you click on your Chime account. The console tree, which is located on the left side the screen, contains a Settings section. Claimed Domains is one of the settings listed in this Settings section. Clicking on the Claimed Domains tab will take you to the Claimed Domains screen. Figure 4.
[Click on the image to see a larger version.] Figure 4: The Claimed Domains screen allows you to associate your corporate domain with Chime. Click on Claim a New Domain to be taken to a screen where you can enter the domain name you wish to associate with your Chime Account. After entering your domain name click the Verify This Domain button.
AWS uses the same process to verify domain ownership as Microsoft when someone attempts to associate a Domain Name with Office 365 or Azure. AWS will ask you to add a specific TXT record (that is, a specific record that is unique to the DNS server associated with the domain name) to AWS. AWS will then query the domain’s DNS server for the TXT record. If you are able to modify domain’s DNS records, you are most likely the domain owner. The verification process can take up 24 hours.
Users who log on to Chime using their corporate email address will automatically be added to their Chime account. To sign up, users will need to download the Chime App here. AWS currently offers the Chime App for iOS, Android Mac OS X, Mac OS X, and Windows.
