I have a client running SBS 2011 with Exchange 2010. When creating email folders within shared mailboxes in Outlook 2010, the folder is created but not visible. We know this, because when you try to recreate the folder, Outlook prompts "A folder with this name already exists. Use another name." Strangely enough, there is one machine running Outlook 2013 and the folder created but not visible on the others is visible there. These shared mailboxes are given full access permissions per the users that are creating these folders within them. Please advise if I am missing something here that only applies to Outlook 2010.
