Unable to access some Online Archive folders only when using Outlook 2013

Daniel Kharman

Hi all,


I am facing a strange issue in my organization where a growing number of staff are unable to access some archive folders but only when using Outlook 2013 (Outlook 2016 and OWA work fine). Said users are able to drill-down into the Online Archive, but when they attempt to expand certain folders, they receive the dreaded 'Cannot expand folders' error message.


I've tested this off the corporate network (at home with no filtering/inspection/proxying), and have the same result, so I don't believe it's network related.


Any thoughts?
