Issue Resolved.

Resolution:

1. Technical critical information: It is very essential to understand what is the significance of the Root Folder of the Outlook IPM Tree folder structure/architecture. Root folder is called namely TopOfInformation It's so much critical that the command documentation pages should also have it's mentions.https://learn.microsoft.com/en-us/powershell/module/exchange/add-mailboxfolderpermission?view=exchange-ps
2. ADD-MailboxFolderPermission -Identity xxx@domain.com:\ -AccessRights Reviewer -User abc@domain.com #this command is to provide top of information folder access
3. Then run command specific to other folders like inbox and sent items. ADD-MailboxFolderPermission -Identity "xxx@domain.com:\inbox" -AccessRights Reviewer -User abc@domain.com ADD-MailboxFolderPermission -Identity "lou@domain.com:\SENT ITEMS" -AccessRights Reviewer -User abc@domain.com
4. I found only 2 mentions that too hidden in the Graph documentations. https://learn.microsoft.com/en-us/outlook/troubleshoot/user-interface/incorrect-folder-names https://learn.microsoft.com/en-us/graph/api/resources/mailfolder?view=graph-rest-1.0

Hi @Shubhansh Singh

Are your delegate and owner in the same environment?

Based on my research, you could try to use the following command to give Read only permission on inbox and sent items folder:

ADD-MailboxFolderPermission -Identity "xxx@domain.com:\inbox" -AccessRights Reviewer -User abc@domain.com

ADD-MailboxFolderPermission -Identity "lou@domain.com:\SENT ITEMS" -AccessRights Reviewer -User abc@domain.com
