Exam MS-203 topic 1 question 91 discussion

I believe that was C Enabling the mail public folder with the HiddenFromAddressListsEnabled parameter set to $True will prevent users from sending email to the folder by hiding it from the address book, but will still allow users to create new items in the folder by using Outlook reference : https://learn.microsoft.com/en-us/exchange/collaboration-exo/public-folders/enable-or-disable-mail-for-public-folder

D is correct

Acording chat GP : To prevent users from creating posts by sending email to a mail-enabled public folder named folder1 while still allowing them to create new items in folder1 using Microsoft Outlook, you should use the following command: D. Set-MailPublicFolder -Identity "\folder1" -AcceptMessagesOnlyFromDLMembers This command sets the mail-enabled public folder to accept messages only from distribution list (DL) members, effectively preventing users from sending email directly to the folder while still allowing them to create new items in the folder via Outlook. Ansver D is correct answer

Correct answer should be B Use the Disable-MailPublicFolder cmdlet to mail-disable a public folder. https://learn.microsoft.com/en-us/powershell/module/exchange/disable-mailpublicfolder?view=exchange-ps

I think this should be B, you need to block email posting, but allow posting through the app. Answer D would only allow messages from DLMember, by post or app https://learn.microsoft.com/en-us/exchange/collaboration/public-folders/mail-enable-or-disable?view=exchserver-2019
