Hi,
This seems to be related to the permissions of the folder, which you can see by running Get-MailboxFolderPermission (ExchangePowerShell) | Microsoft Learn in EMS:
Here are some of the roles in it and the corresponding permissions:
· NonEditingAuthor: CreateItems, DeleteOwnedItems, FolderVisible, ReadItems
· Owner: CreateItems, CreateSubfolders, DeleteAllItems, DeleteOwnedItems, EditAllItems, EditOwnedItems, FolderContact, FolderOwner, FolderVisible, ReadItems
If you want to change the permissions, run:. Set-MailboxFolderPermission (ExchangePowerShell) | Microsoft Learn
Here is an example: Set-MailboxFolderPermission -Identity share1@mike.com:\Inbox\folder1 -User default -AccessRights Owner
This command will change the default user's permissions for folder1 in share1 to Owner.
For a list of specific permissions that can be set, see:Set-MailboxFolderPermission (ExchangePowerShell) | Microsoft Learn
Hope this helps! Please feel free to contact me for any updates.
