I am new to SharePoint and CSOM, but I am comfortable in PowerShell and .NET. I’m trying to do the following tasks in SharePoint Online:

1. Get the list of users in a particular named group
2. For each user, create a folder
3. For each folder created, break inheritance with the parent folder and assign exclusive access to its respective user

For the first task, I’ve tried the following code:

# Get a specific group by name $  allGroups = $  web.SiteGroups $  ctx.Load($  allGroups) $  ctx.ExecuteQuery() $  group = $  allGroups.GetByName('My Group')  # Get all users in the group 'My Group' $  users = $  group.Users $  ctx.Load($  users) $  ctx.ExecuteQuery() 

The GroupCollection.GetByName method always gives me a “collection has not been initialized” error. I know that $ allGroups is initialized because I am able to query other properties such as $ allGroups.Count. What am I doing wrong? Is there another way to retrieve a particular group by name?

The second task should be straightforward. I already have successfully created new folders, so I just need to use a foreach loop to accomplish this step.

I haven’t been able to test the third task yet, but I have seen plenty of code samples online for breaking inheritance, and I expect that adding a permission for a user won’t be too difficult. I’ll edit this question if I run into problems, but in the meantime, some sample code to get me started would be very appreciated.
