I have an imap account served by SBS 2003 Exchange server, and have setup it in mail app on my Windows 8 Pro . When I receive emails and try to open the attachment such as jpg, PDF or Word document , it shows error “one or more files cannot be downloaded, TRY AGAIN”. The Windows RT also has the same issue with any file regardless of regardless or size on Surface tablet. However, I am able to open them on my Android and iPad devices.
If you can not open any attachments whinin Windows 8 mail app, try the following tips to fix the issues:
* Make sure you have installed the lastest Windows updates and Mail application.
* This seems to be a security issue with file permissions. The workaround is to do through the Webmail web interface or use the Outlook Web Access.
* Installing Touchdown app is the easiest solution. The popular email client works fine on both the Windows 8 Pro and RT. It supports for Email, Calendar, Contacts, Tasks and Notes syncing for Exchange 2010 servers, and offers a smiply way to download of attachments.
