got a very strange issue with the Ionic dll. We have an email enabled SharePoint document library into which various users email documents including zipped files. Up to now the Ionic dll has worked fine but last week a zip file didn't get unpacked. When
the primary user re-emailed the document it still didn't unpack. I asked another standard user to email the file and again it didn't unpack.
When I email the zipped file it does unpack but what is really odd is that when the document is emailed from a team email account the zip file unpacks.
I'm at a loss to explain this behaviour, can anyone shed any light on it? Does the user profile of the person sending the email have any impact?
