I have people who call into the service desk stating that since the move from office 2007 to Office 2016 (yes, we do still have some users using 2007), they are unable to view emails in Outlook 2016 that are more than 30 days old, and they get a message that there are more items stored on the server, click here to view them. Sometimes checking the download public folder favourites checkbox under the cached exchange mode settings will do the trick, and sometimes it won't. What causes this, and what is a shorefire way to fix it, if you know? Thanks.
