Sharing a Planner Plan 1 plan with a guest user

Hi there,

Looking for advice on what settings may be required to ensure that a guest user from another tenant can access a Planner Plan 1 plan which has been shared via a user in my tenant. Any assistance would be greatly appreciated!

 

Guest user error message:

"You do not have access to this plan. Ask any member to add you to the plan."

 

  • Microsoft Planner Plan 1 user cannot share plan with guest user from another tenant
  • Both users have Planner Plan 1 license assigned, the guest user has it assigned to their guest account on my tenant
  • The Plan is shared in a Microsoft Team, of which both users are members
  • The guest user has been added to the Plan
  • The guest user has also tried opening the Plan directly via the Plan URL which was shared by the creator
  • The guest user gets error message: You do not have access to this plan. Ask any member to add you to the plan."
  • Other non-guest users from my tenant are able to access the Plan without any issues
  • The guest user has selected their guest account from my tenant within their Teams app from their own laptop, and upon signing into the guest account, no Planner tab is listed for the user, and there is no ability to add it

    Hey mate, 
    Planner does support guest users, but it’s not smooth. Microsoft’s docs say guests can be added through Microsoft 365 Groups and they can do things like create tasks, edit details, and add files if group settings allow it. But they don’t have the same rights as full tenant members, so it often feels broken.

    The error you’re seeing usually happens when group guest access isn’t set up properly in the tenant, or because of the way Teams and Planner link up. Even if the guest has a Planner Plan 1 license, that alone doesn’t fix it, the license doesn’t override group settings.

    Guests also miss out on things like task assignment emails, and they can’t manage some plan settings. Basically, it works in theory, but in practice it’s hit and miss.

    Common fixes are:

    1. make sure Microsoft 365 Group guest access is enabled
    2. or just give them a proper user account in your tenant
