"The group no longer exists. It may have been deleted" message on public group events web part.

Hi Nick,

I have tested it again. Here are the details and results.

Steps:

I used Account A to change Site A's group privacy from Private to Public, and then I used Account B to access this site.

Please note that Account B was not in Site A's group, and the Events web part and the Group Calendar web part connected Site A's own event list and group calendar.

Results:

1. On Account B's side, the Events web part worked well, and I could see the events.
2. On Account B's side, the Group Calendar web part did display the error "The group no longer exists. It may have been deleted". However, when I used Account B to edit the page, remove the Group Calendar web part, re-add the Group Calendar web part, publish the home page, then click the "Sync Calendar" button, I could see the events.
3. If I use Account A and go to another team site whose group privacy is "Private", add the Group Calendar web and the Events web part, and set them to connect to Site A's event list and group calendar, they all work well.

Hi Nick,

Thanks for posting back.

Regarding your queries, since the group privacy is Public, even if you are not in the group, you should be able to access the event list of this site (can see events in the Events web part) and access the group calendar (can see events in the Group Calendar web part).

I have tested it again on my side, and you can view the details and results in my next reply. In summary, they work well as expected on my side. Only for the Group Calendar web part, you will need to remove and re-add it again.

I understand this used to be a "bug" and users had to accept the workaround, however, based on my test, the problem should not happen now. I recommend you check the following points.

1. Please make sure the group is a public group. You can check it when accessing the site.

2. Please remove the existing Events web part and the Group Calendar web part, re-add them, then check again.

If the error message still appears, please contact your admin or IT department to raise a support ticket via Microsoft 365 Admin Center> Support> New service request. That support team there will have the correct channel and resources to help you investigate more and find what exactly reason has caused this problem.

Sorry for the inconvenience that happened to you. Appreciate your understanding and patience.

Hello George,

No, I meant the events web part. But even trying to use the group calendar web part presents the same problem. The group does not show as an option. I am not a member of the group, but that shouldn't matter since the group is public, right? If I'm an admin of a Sharepoint page I should be able to add any public group calendar, right?

Even trying to add in Outlook for web presents the same issue. I cannot add the calendar.

This is a new group created within the last month or so.

Hi Nick,

For "public group events web part", I suppose you mean the Group calendar web part, not the Events web part. The Group calendar web part is used to display events in the group calendar. If not, please point it out and let us know.

If so, I did find some threads mentioning this situation and workarounds, however, I have tested it on my side, and it works well after changing the group from Private to Public. So, troubleshoot the situation, please check the following points and share the results with us.

1. Is the group a newly created group or an aged group?
2. As the Group calendar can't find the group, please check if you can find the group in Outlook for Web. Go to Outlook for Web, under the Group section, click "More", then check if you can see this group or not.

If you can see this group, please select the Calendar button and check if you can access the group calendar and see its events. If you can, please go back to the site, edit the home page, remove the existing Group calendar web part, add a new Group calendar web part, and then check again.

If you can't find this group, please click "Discover group" to search for this group.

We look forward to your response. Thanks for your cooperation.
