It works, but I have hundreds of sites to block. First I would need to list all sites and then one by one block them.
Is there a way to automate it and BLOCK all sites?
I want to lock sites temporarily. This lock prevent users that has a personal site to use them (new ppl are blocked by MySite setting).
I contacted Microsoft directly and they provided me with some data - they told me that I should use ForEach, but I have no idea how to use it, and they won't help me any further cause it is against some policy.
