How can we improve Office 365 Groups?

Ability to Customize Office 365 Group's Welcome Email/Message

Since the Office 365 groups are now the center stage/focal point for the majority of the Office 365 products/services, it will be great to have the ability to send the customized welcome emails whenever we add someone to the group either via the user interface or using Microsoft Graph API.

This functionality can be set at Tenant level or at individual Office 365 group level. By default, it should be off.

The reason this functionality is important because the default welcome message does not contain enough information to let the users know what this group is about and what will be its usage. The customized welcome message will help organizations to communicate effectively the intended usage of the Group and other relevant information. The customized welcome emails are really helpful for non-technical users.

If Microsoft can not provide this functionality via User Interface at least this functionality should be available via Microsoft Graph API. Right now the only way to suppress the Group's welcome email messages is via Spam Filter (which is not a viable option) and send customized emails to avoid duplicate welcome email messages.

While you cannot customize the default welcome mail for Office 365 Groups, disabling the welcome mail is possible with an extra parameter in the Set-UnifiedGroup cmdlet in Exchange PowerShell: -UnifiedGroupWelcomeMessageEnabled:$false. See

Use this as a part of a custom group creation flow if you would like to restrict and/or customize the welcome mail for many groups across your tenant.

    It would be useful if the welcome message could be enabled/disabled during the creation of the O365 group instead of controlling this at the tenant level. Also agree that having the ability to customize the welcome message would allow for a more effective means of communicating to the users.

    Since the default information is not valid for us (not using Outlook 2016) and the main part that we use in a Office365 group is the Team site in SharePoint, we need at least the link to the site in the mail.
    We are in a multi tenant (20+ domains and all not using the same platform for collaboration, we need to turn of this mail for only some domains. Today we have created a rule under Mail flow to capture this mails so now no information is sent (for our domain).
    At least something like when you add a new member to a SharePoint group where you can add info to the mail and also avoid to sent it.

    FWIW there's a setting on the O365 Group: "WelcomeMessageEnabled" which controls this behaviour. Per "You can use the following command to suppress the welcome message for any new users added to the group as a member. ... pass "false" as the value to suppress the welcome message.

    Set-UnifiedGroup <groupname> -UnifiedGroupWelcomeMessageEnabled:$<true/false>
