Send and Control Emails to Microsoft Teams Channels

If you want to send an email to a channel in Teams, use the channel email address. Once an email is part of a channel, anyone can reply to it to start a conversation.

Basics

By default, any channel in a team can receive email from any sender. Teams supports this capability by assigning email addresses to channels on an on-demand basis and using inbound email sent to create new conversations in the target channels.

Control the Feature via Teams Admin Center

If you’d prefer to impose some control over email communications to Teams, head for the Org-wide settings section of the Teams admin center and select Teams settings. The Email integration section allows tenants to:

• Disable or enable the ability of users to send email to channel email addresses. The default is On.
• Create an accepted list of domains from where email can originate. The default is to accept email from any domain. Make sure to include all the domains used to send email in the list of accepted domains. Individual team owners cannot override the set of accepted domains defined for a tenant.

PowerShell

Set-CsTeamsClientConfigurationcmdlet from the Teams module may be used to control the fature with PowerShell.

$AllowDomains = "Connecion.com;CNXNcloudsupport.onmicrosoft.com"

Set-CsTeamsClientConfiguration -RestrictedSenderList $AllowDomains -AllowEmailIntoChannel $true

Get-CsTeamsClientConfiguration | Select AllowEmailIntoChannel, RestrictedSenderList

 

Note: It can take an hour or so before the addition or removal of a domain from the list becomes effective.

 

Looking Emails to Teams Channels in SharePoint Online

When Teams creates a new conversation, it also stores the copy of the original message in a subfolder of the channel folder in the SharePoint Online site belonging to the team.

 

Channel Email Address:

To retrieve the address of a channel, use the Get email address option in the channel menu and then use the Copy button to copy the email address to the clipboard.

 

Know Issues in Email Failures

The following are several reasons why sending an email to a channel can fail:

• The feature is not enabled by your IT admin. Contact your admin for more info. Your admin can configure this feature by using email integration under Teams org-wide settings.

• The channel settings restrict who can send email, such as the channel moderation setting being turned on. Check with a team owner or a channel moderator to see if you have permission to send email to the channel.

• The email contains more than 50 inline images.

• The email has more than 20 file attachments.

• The email has an attachment that's more than 10 MB.

• The email includes the channel email address as part of a distribution list. Make sure that the channel email address is being used directly.

• The SharePoint folder associated with the channel was deleted, renamed, or hasn't been synced. To revert a renamed folder or sync a folder:

  • Go to the channel and select Files > Show actions >Open in SharePoint.

  • In the upper-right corner of your screen, select Open the details pane >More details.

  • Under Activity, locate the original folder name, and then rename the folder using the original name.

    

  • To sync a folder: Go to the channel, and select Files >Sync.

    

• Anti-spam protection is blocking the email. Check with your IT admin to make sure that the domain used in the email address isn't being blocked. Your admin should also make sure that other Teams management settings allow email to be sent to the channel.
