Love the ability to add task to a group with Planner but please have task that have an expiration date automatically add themselves to the Group calendar and the Assigned resource's calendar automatically.

In Microsoft's April update for Office 365 groups they mention the Azure AD naming policy is coming but only for Azure Premium customers. This should not be the case. Proper management of Office 365 groups should include naming policies. Without naming policies, there is a large potential for namespace collisions for folks who do not use the Azure AD premium service. This is something that should be available to all not just Azure AD premium customers.

sometimes the notifications don't show when get new updates in Microsoft Teams so have to remember to go in and check for new stuff.

Please give us the option to hide the Groups section altogether on the email login page - I'm sure it's a nice feature for some, but there's some of us out here who don't and won't use the Groups feature, so it's annoying to always have to hide in upon logging in.

It's a security matter. Now person can share Group membership to his external account and use the group with that account even after he leaves our organization. Can we have an option that informs admins if there's a Group that has only external user(s) or remove automatically all external users from a Group that has no internal users left in it.
