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.
Thanks for the feedback. We are considering implementation of “Secret groups” in the near future.
Please consider leveraging Microsoft To-Do https://todo.microsoft.com/en-us
Microsoft To-Do is not the same as Planner. Planner provides an easier and more detailed task management system. Simplicity, power, and flexibility is what Planner needs. Its why I haven't moved to it from Trello.
Thanks for your feedback. We are currently thinking about this. Can you please let us know what scenarios your organization uses shared mailboxes for and what options do you use. This will help us.
I would like to get our users away from traditional shared mailboxes. In most organizations I've worked with, shared mailboxes tend to be a black hole of data, anti-collaborative, and large and cumbersome to manage. This is in addition to the other limitations other have mentioned as far as accessing shard mailbox across Outlook experiences.
Thanks for this request. We are rolling out the links to planner boards for groups in Outlook desktop from the group card, so that should help get to the planner task list.
This request seems to be asking for the Outlook desktop tasks list to also show planner tasks. Can you help us understand the use cases and details on the actions you expect to perform with planner tasks in Outlook?
I would like to see a unified task system and I think Planner best fits this or at least all experiences have the same backend somehow. Right now, you create tasks in OneNote, SharePoint, Outlook, Planner, ToDo.
Thinking about it more than 2 years ago. Any update?
