powershell – Prevent Outlook Online users from sharing their mailbox folders

I’m in the process of migrating a school domain from Exchange 2016 to Exchange Online (Full Hybrid). I’ve noticed that in Outlook on the web, users are able to right click their inbox (or any other mailbox folder), click Permissions and give other users read and write access to their folders. I want to prevent pupils from accessing this feature, or at least prevent them from adding permissions/sharing their folders (I.e. read only access). Unfortunately, pupils occasionally enjoy trying to delete each other’s work etc so I think it’s best they don’t have access to folder permissions.

Mailbox Folder Permissions

From my research I have found that anything which isn’t covered by an Owa Mailbox Policy can be controlled using RBAC (I.e. Role Based Access Control). So I set up and assigned a policy to a test account and removed access to the Add-MailboxFolderPermission, Remove-MailboxFolderPermission and Set-MailboxFolderPermission cmdlets as shown below.

New-ManagementRole -Name "MyBaseOptions-ForPupils" -Parent "MyBaseOptions"
New-RoleAssignmentPolicy -Name "Test Pupil Role" -Roles "MyBaseOptions-ForPupils", "MyMailSubscriptions"
Get-Mailbox -Identity test@domain.com | Set-Mailbox -RoleAssignmentPolicy "Test Pupil Role"

Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsAdd-MailboxFolderPermission"
Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsSet-MailboxFolderPermission
Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsRemove-MailboxFolderPermission"

This didn’t work, so I also tried removing the following cmdlets to see if it would remove access to the Permissions feature altogether, but wasn’t sure if this would cause any problems.

Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsGet-MailboxFolderPermission"
Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsGet-EXOMailboxFolderPermission"

I haven’t noticed any problems, but the feature is still accessible and the test account can still add, edit and remove folder permissions. I have checked that the cmdlets I have removed are not in the MyMailSubscriptions role (which I also assigned to the test account) and they are not.

As a test I ran the following commands and the Auto Reply settings disappeared from the UI a few minutes later, so the policy has definitely applied.

Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsGet-MailboxAutoReplyConfiguration"
Remove-ManagementRoleEntry -Identity "MyBaseOptions-ForPupilsSet-MailboxAutoReplyConfiguration"

I also authenticated PowerShell as the test account I.e. Connect-ExchangeOnline -UserPrincipalName test@domain.com and confirmed that the account is not able to access the cmdlets which I removed.

Is anybody able to tell me how to get this working please, or if it is even possible?

linux – Hide specific folders for a sftp user? Within chroot

when using vsftpd there is an option to hide files or directories that matches a certain pattern in the variable hide_files. Can something similar be achieved when using SFTP/SSH?

Want I want to do is to let people log in to a chrooted directory where only some specific folders are hidden. Once logged in the users can upload files, and download files in the available folders. Also another User can only read them.

I have done a chroot jail for Users, but this is not possible because some Users need to see all Folders in the Chroot Jail.

bash – Iterate over the folders within a file

I have two folders, Controls and Patients within each of them there´s several folders, one of them called Runfirstall. I have the next code:


for group in Controls Patients; 
    echo $group 
    for folder in $DIR/$group/!(Runfirstall)/
        name=$(basename "$folder")  
        echo $name 

Which fives me this error:

./test.sh: line 7: syntax error near unexpected token `('
./test.sh: line 7: `    for folder in $DIR/$group/!(Runfirstall)'

Why is this incorrect?

powershell – Shell command to delete all files in specific range of folders

I’m working on an upgrade to an application and I need to delete all of the files in several folders so that the the files are regenerated when users login. The file path is Master#(where # is the workspace no. in the app)MRHomepage. The issue is, there are 136 MASTER folders, so I wanted to see if there’s a way to run a script to go into each of these folders and delete all of the files.

So to summarize it, I want to have this script go into each dbMaster#MRHomepage folder and delete all of the contents. I know how to do this for a single folder but not for each folder through the same script.

Remove-Item XdbMASTER1MRHomepage*.txt* -Include *.txt.ycache* -Confirm$false

Is there a way to wildcard the MASTER# in the url link? I don’t want to delete anything other than what’s in the Homepage folder.

directory – Can’t Apply Changes to Permissions Within a Folder’s Enclosed Files in Ubun

Issue with the GUI
I’m using Ubuntu 16.04 LTS. I am trying to allow all enclosed Files and Folders to have full Read and write access as well as Create and delete files. Currently it is set to Read and write and create and delete files for both the Owner and Group, but Others is set to Read-only and Access Files. I am trying to change Others to full Read and Write and Create and delete files, but every time I try and change the permissions and press “change” it doesn’t actually change anything. Any idea as to how I can fix this?

How to implement multiple wallet folders located out of the bitcoin blockchain folder?

After substantial research I could not find any solution for this seemingly simple implementation of the Bitcoin-Core app.

Here is what I am trying to achieve:
Running a full node on one computer require up do 400GB of drive storage. It appear, after all my research, that if one wants to access more than one wallet from the same computer, it would be required that each wallet be run from a different folder altogether, otherwise the Bitcoin-Core will act strangely, refuse to launch, or ask the user to create a new wallet altogether. Add to that, would also be required that each wallet be launched with a different shortcut, which is well acceptable.

I am running a Windows 7 computer that can hold 1TB on a secondary data hard drive. The first drive is an SSD and is strictly utilized for the OS and software installation. Holding the whole bitcoin blockchain is OK but holding 2 copies or 3 is out of the question, besides would be kind of ridiculous since X times 400GB of the same data makes no sense.
What I am trying to do is be able to launch a different wallet via its own shortcut. After several experimentation the only way I found to do this would be that every time I want to run a wallet I have to replace a whole bunch of files related to that wallet into the bitcoin folder. This is a tedious task and a relatively unsafe way to do things. Such practice is prone to errors and could potentially be risky to lose some bitcoins.

I’ve experimented with the shortcut option


but this doesn’t work for some reason. The parameter is completely ignore without generating any error. The only way I found that could work would be to maintain the whole blockchain 3X into 3 different folders and launch any of them with the appropriate shortcut. An option that require 1.2TB and makes no practical sense since it is utilizing so much hard drive memory storage.

So here is the question:
How can I store a specific wallet located in FolderA that is completely different then D:Bitcoin
(were D:Bitcoin would be the complete blockchain location) ?

If I could do that then I could also create any number of FolderB, FolderC, FolderD that would hold my different wallets and that I could launch any of those wallets ( not simultaneously ) when I need to do a transaction. All these folders could store the wallet files but not the whole blockchain.
Thanks for your help

sharepoint online – Working with large amounts of folders

I’m in SharePoint Online, where I have to copy data from one list to another. My code already works on low amount of folders, but I have problems with large amount of folders.

LibraryA: Contains 50,000+ folders structured like:

- Folder "ABCOEQ":
- Folder "BCOEQW":

I have operations that work on these folders such as:

private static void CopyToDestination(ClientContext context, FolderCollection folders)
private static void CreateFolder(ClientContext context, string listName, string folderName)
private static Folder GetFolderByName(FolderCollection folders, string folderName)

When loading folders inside a RootFolder of a List I receive an exception that the list is too large. My whole program gets stuck on:

List sourceList = web.Lists.GetByTitle(SOURCE_LIST_NAME);
FolderCollection folders = sourceList.RootFolder.Folders;

After loading them I refer to them like that:

foreach (Folder folder in folders)
       FolderCollection subfolders = folder.Folders;
       // Logic to manipulate files and folders inside

How can I get FolderCollection that takes all of the folders or read it by batches of for example 500 folders?
