Planner - Change E-Mail

[Konrad Herrmann]

Hello Community,

I have a question about Planner, especially the e-mail domain used by Planner

We registered 4 domains in our tenant. Domain-A is registered as the default domain for this tenant. In about 4 months we must change the default domain from Domain-A to Domain-B. So Domain-B is than registered as a new default domain.

 Now I ask me:

When I create a new Planner / Task with the email address " Planner-Name@Domain-A.com”, unfortunately i find no way to edit the e-mail domain?

What happens, if I change the default domain in 4 months to Domain-B? Must I create all Planner Task's new? Because I have no way to change the email addresses of the created Planner Task's?

Best regards

Konrad

Hi Konrad,

I think the simplest approach would be to use PowerShell to manage all of these. A recursive script or a script with an input of the group identities you want to modify would work.

The Set-UnifiedGroup cmdlet will be able to change the email addresses of the groups for you. See more at the TechNet link below;

This is currently possible for Groups, but not so sure for Planner: https://support.office.com/en-us/article/Multi-domain-support-for-Office-365-Groups-Admin-help-7cf56...@Tony Redmond might share more insights on this

Planner depend on Groups for email etc., so you can absolutely change the email address of a group as long as you use one of the domains registered for your tenant.

Set-UnifiedGroup -Id MyGroup -PrimarySMTPAddress MyAddress@mydomain.com
