Hi! I have very serious and urgent problem.
I have migrated a Onprem Server 2010 to SharePoint Online for a customer. Everything went fine, i had to create new pages because this is a management system with visios on the pages. No problems there and they have som document library and one list.
After the migration i checked the rights and gave them new rights to the newly created pages. After a while we noticed that noone except the users with full rights can access any pages of the migrated site.
I have tried everything as I have come up with, I have escalated it to Microsoft with no luck.
Can someone pleas advice?
Things that have been tested:
- Give users read, edit, with no luck, only when I apply full rights they can access the pages.
- Request accesspermissions from users poit of view, accepted it from admin requests. Cleared cache, access the page from email and so on, nothing works.
- Restored user groups.
- Break inheritance, I hope I have done this on all pages, document librarys, lists and so on. Waited 12-24 hours before applying new rights
- Break inheritance on masterpage, applied new rights, nothing works.
- Removed all user groups except admin, what happens if I remove admins aswell, can I apply adminrights again or is the site lost?
- Used Sharepoint designer to copy page to another site, doesnt work.
- powershellscripts
- There are no sync between Active directory and M365.
- The migration tool that has been used is Microsoft Sharepoint migration tool
I´m clueless, please advise me, really dont want to start everything over again!
