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 https://docs.microsoft.com/en-us/powershell/module/exchange/users-and-groups/set-unifiedgroup
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.Anonymous supported this idea ·

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.
