Question

Something went wrong when trying change a member to an owner in a Microsoft 365 group

Jonathan Ridgway 0

I am the owner of a group, and am trying to add a member as an additional owner. I've tried two methods. In Manage Groups, under 'Owners' tab, I have clicked on the Add button. It says 'Something went wrong'. Under the Members tab, I've clicked on the 'Convert to Owner' button, and it says 'Something went wrong'.

It is a group I set up through the non-profit page. I'm wondering if owners have to have an 'onmicrosoft' email to be an owner? Otherwise I'm out of guesses. Please help.

Moved from Microsoft 365 and Office | SharePoint | Other | MacOS

Dear Jonathan Ridgway,

To better understand the issue, could you please provide a little more detail about the exact steps you are taking when you try to add or convert the member to an owner? In particular, please let me know where you are managing the group, for example, from the Microsoft 365 admin center, SharePoint admin center? Please take a screenshot showing the error then share it with me.

As an additional test, could you please try changing the member to an owner directly from the Microsoft 365 admin center, as shown in my screenshot?

Untitled

Open the Microsoft 365 admin center.
Select Teams & groups > Active teams & groups.
Select the affected Microsoft 365 group.
Open the Membership tab.
Select Members.
Select the member you would like to promote.
Select Make owner.

Please correct me if I'm misunderstanding. Thank you very much for your valuable time and your cooperation.

Looking forward to your response!

Dear Jonathan Ridgway,

Based on the screenshots, it appears that you may only be a SharePoint site owner. Please contact your Global Administrator and ask them to follow the steps I provided above in the Microsoft 365 admin center to add the member as an owner.

Dear Jonathan Ridgway,

I hope everything is going well on your end.

I’m following up on the support thread we've been working through together. I wanted to check in and see if the information I shared in my previous answer helped clarify the issue you were experiencing.

Hi Jade. No I gave up because I don't have a global administrator. I set up the sharepoint and the group earlier this year with limited knowledge of what I was doing. We are a small not-for-profit organisation. Now I want to pass it on to others so I can leave, but don't seem to have permissions to be able to do so. I'm monumentally stuck.

Dear Jonathan Ridgway,

Thank you for clarifying the situation.

Since there is currently no Global Administrator available to make the required changes, I recommend contacting Nonprofit support and raising a support request. Please explain that your organization currently does not have access to a Global Administrator account and that you need assistance regaining the appropriate administrative access so that ownership of the Microsoft 365 Group can be transferred.

Hope this helps. Thank you very much for your valuable time and your cooperation.
