Planner - Admins of group can't access plans, but members can

Question

All of a sudden plans I have made, I no longer have access to. It says I no longer have access, and to contact the admin. However, I checked with a colleague who is also an admin of the group, and they have the exact same issue. The group is 'marketing' and doesn't show up for me to share when a create a new plan, or select share plan. but my colleague, who is a member can see this.

I am also getting this error message when i view other plans other people have created.

You no longer have access to "[Moderator note: personal info removed] ".

please can someone advise?

Hi @Annika Rieley,

Thanks for taking the time to explain what’s happening. Planner access depends on the Microsoft 365 group behind it, so if a group owner or admin isn’t also listed as a member, they can unexpectedly lose access to the plans. Meanwhile, users who remain in the group’s Members list are still able to see and work with those plans without any issues.

The first thing I’d suggest is checking the Marketing group in the Microsoft 365 admin center and confirming that all affected users appear under Members/Owners. If someone is missing, adding them back in usually restores access. Even if the users already show as members, it’s often worth removing them and adding them again, then giving the system a few minutes to sync, as this can clear up permission mismatches behind the scenes.

It’s also a good idea to take a quick look at the SharePoint site connected to the group, since Planner relies on that site for storage. Please navigate to the site’s document library, open the library settings, and review the permissions there. Make sure the correct group still has the necessary access. If the permissions look incomplete or broken, re‑granting them can help. Microsoft has a helpful guide on adjusting SharePoint library permissions here: Customize permissions for a SharePoint list or library - Microsoft Support

Please note that some of these checks require the right admin or site owner permissions. If you don’t have those, it would be best to ask your Microsoft 365 or SharePoint admin to help review this with you.

If you try these steps and the issue continues, please feel free to leave a comment under this post with any updates. That’s the fastest way for me to get notified and follow up with you more effectively.

Thanks again for bringing this up, and I hope this helps get your Planner access back on track.
