Question details

The user is trying to add a Teams channel email address or an external user's email into a SharePoint Person or Group column, but the system rejects the input or cannot find the user.

How to Fix a Teams Channel Email Address Not Being Accepted in a SharePoint Person Column

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Attempting to assign a list item or document to a Teams channel or an external collaborator using the standard Person or Group column in a SharePoint list.
Observed behavior: The SharePoint Person or Group column does not recognize the arbitrary email address or Teams channel email, as it exclusively searches the organization's Microsoft Entra ID (directory) for valid user accounts.

Before you start

Verify that your Microsoft 365 external collaboration settings allow you to invite guest users, and ensure you have administrative rights in Microsoft Entra ID.

Solution 1Recommended

Invite External Users as Guests via Microsoft Entra ID

To allow an external person's email to be selected in a Person or Group column, you must first register them as a guest in your organization's directory.

The Person or Group column is strictly linked to Microsoft Entra ID. It will not accept external emails until they are formally invited and added as guest users to the directory.

Access Microsoft Entra admin center

Log in to the Microsoft Entra admin center with appropriate administrative privileges and navigate to 'Users' > 'All users'.

Invite the external user

Click on 'New user' and select 'Invite external user'. Fill out the required email address and display name fields, then send the invitation.

Accept the invitation

Have the external user open the invitation email in their inbox and follow the prompts to accept the guest invitation.

Select the user in SharePoint

Once directory synchronization is complete (which may take a short while), return to your SharePoint list and type the guest user's name into the Person or Group column.

Invite External Users as Guests via Microsoft Entra ID

Restriction on Teams Channel Emails: While this method works for actual external people, a Teams channel email address is a routing address, not a valid user entity. It still cannot be added as a guest in Entra ID.

Solution 2

Use a Text Column for Teams Channel Email Addresses

Since Teams channel email addresses cannot be registered as directory users, use a simple text or hyperlink column as a workaround.

Frequently Asked Questions

Why does the SharePoint Person column reject my email entries?

The SharePoint Person or Group column is designed to validate inputs against your organization's Microsoft Entra ID. If the email address you type does not belong to a licensed internal user or an approved guest user in the directory, it will be rejected.

Can I add a Microsoft Teams channel email as a guest user?

No. A Teams channel email address is used for routing messages to a specific channel location, not for identifying a physical user. Therefore, it cannot be added to Entra ID as a guest or selected in a Person column.

How long does it take for a new guest user to appear in SharePoint searches?

After an external user accepts the Entra ID guest invitation, directory synchronization needs to process the new account. This typically takes anywhere from a few minutes to an hour, but can occasionally take up to 24 hours in large environments.
