i have a problem with some users. I have created a separate group and added 200 users to it.

200 users have access to the site and enter it with a special username and password.

There is no problem, but suddenly some users can not enter the site and error :

If no changes are made, some users' access will be automatically and suddenly removed

Please Guide me where the problem comes from and how to fix it

    Hi, @Leili vazietan ,

    Before we start, I would like to confirm that if you are using SharePoint Online or other version of SharePoint. You can use this tutorial to find which product you are using now. If just like your tag, you are using SharePoint Online, are all the 200 users tenant members? Is there any external user? Is the group a M365 group or security group? You can check the group in M365 admin center> groups

    As you mention, you have a group of 200 users. The scenario is like this: Right before, the group works fine and all the users can access the site. And in a sudden, a certain part of the group members lose their access to the site. They get error Sorry, this site is not shared with you when accessing. Meanwhile, other users still can access the site.

    First thing, we shall always check the current user permission in that site. You can follow this blog to check both the group and users with issue. If in site level, the user permission seems to be fine, we can move to next step.

    Pick up a user account with issue, remove it from the group and re-add it. Check if this resolve this issue. And you can try to add the user directly and check if the issue is resolved

    Feel free to reply with any update.
