In some scenarios it is required to put a site in read only-mode, for example a project site, or to simply just remove access to it.
From the SharePoint Online Admin Center there is no way to lock your site, or to put it in read-only. There are two ways to achieve this, one is through Powershell, the other one through the Site Settings of your Site Collection.
You’re looking to set up an international Office 365 environment, and cannot find anything about it? That’s correct, because there is nothing like that at all. Neither a guide with best practices.
Some people suggest to set up a tenant on each continent. Give this a thought for a minute, and you can come up with even more questions.
- You can only use your domainname on one tenant, how to handle the other tenants?
