Hi Ananthi -
I think our Support Team will be the best resource for your email issue and the attachment issue.
Could you please submit a Support Ticket for each problem? You can easily do so by logging into ALMComplete / QAComplete, look for "Help Center" at the top right of your screen. Click on Help Center, then Create Support Ticket.
Please take some screen shots of what you are seeing and include them. That will help us get you set up correctly.
The email issue is likely a configuration issue.
The attachment issue might be either a server issue (MIME types on the server) or a browser issue.
Thanks!
