Folders in your mailbox have name conflicts
Microsoft Outlook <firstname.lastname@example.org>
One or more folders in your mailbox have name conflicts with others or system reserved names.
Folders with these names can't be downloaded by your IMAP e-mail program.
Please connect to your mailbox using your Web browser and rename those folders. Once renamed, those folders will be displayed in your IMAP e-mail application correctly.
