This guide will show two simple but accurate steps to add a new guest user to your Azure AD tenant.
Before you invite an external user to your Azure AD tenant, you must add a mail contact for the user in Exchange Online. After that, you can invite the user to join Azure AD.
Inviting a user without first creating a contact causes all sorts of problems. One of the problems you may notice is that other users will not be able to add the external user’s calendar to their calendar.

As I mentioned in my introduction, the right approach to adding an external user to Azure AD is to create a mail contact for the user before inviting the user.
Follow the steps below to do this.
Suppose you have already invited a user with some problems, open Azure AD and delete the user. Then, one the User -> Manager section, click “Deleted user (preview)” and delete the user permanently. Give it about delete minutes before proceeding with the steps below.
- Open the Exchange Online Admin Center and sign in with an admin account.
- Next, navigate to Recipients -> Contacts.

- Then, on the Contacts page, click “Add mail contact.”

- When the Set up the basic information opens, complete the form – see screenshot below – and click Next.
Make the alias the FirstNameLastName. Also, enter the email address of the user you will invite from Azure AD (next section).

- Then, if you wish to enter the optional information, expand the sections and enter the data. When you finish, click Next.

- Finally, review the user’s data and click Create.

Add the External User to Azure Active Directory

After adding a mail contact for the user, follow the steps in this section to invite the external user to join your Azure AD.
- Open the User node in Azure AD by clicking this link – portal.azure.com – then sign in with a user with the appropriate permission.
- Then, click the + New User icon and select Invite external user.

- Finally, enter the user’s email (required) and any other information you wish to include and click Invite.

Microsoft Azure will send an email to the user. The user should open the email, click the “accept invitation” link, and then follow the wizard to complete the signup process.
