I want to see all various site permissions which user has in all site collections - globally within my organization. Office 365.
My idea is a Powershell script which would make a report about all/specific user’s permissions on SharePoint sites, subsites, lists etc., dumped do csv.
There are hundreds of sites so I know the script would have to go by batches. I don't know how to search for a specific person, so I would search for a whole site permissions and then filter out csv.
At this point it looks pretty complicated and I have a basic idea of Powershell posibilities. So I need your opinion how to manage such a big topic and how to bite the script over different sites? Recently I found information only about execution in site collection.
Best Regards
