When retrieving folders list with Outlook REST API (beta endpoint)
I get the complete list of folders. But I also get some hidden/ignored folders that are not displayed in usual Outlook clients. I would like to ignore such folders as well.
I tried to forge a request using SingleExtendedProperty and PigTagAttributeHidden
https://outlook.office365.com/api/beta/me/MailFolders?$select=Id,DisplayName,ParentFolderId,ChildFolderCount,UnreadItemCount,TotalItemCount,SingleValueExtendedProperties&$expand=SingleValueExtendedProperties($filter=(PropertyId eq 'Boolean 0x10F4'))
In the results this property is always marked as false even for these "ignored" folders.
Is there another way or fix to achieve this?
