And is such occurrence common? ____________________ Some days ago I created a gmail account for the first time. I read that it's the best for safety, so I updated all my work email contacts and changed all my important emails to this gmail (like Steam, ebay, paypal etc etc...) Last Friday I sent an email from my work pc (using an @live.com account) to this gmail account, attaching an .xls file. The email went to my 'sent items'. This email never arrived when I checked from home (I checked all the folders). 3 days later, today, I rechecked the @live account and confirmed that the email was really in my 'sent items' and that no notification of non-delivery had arrived. I resent the email today, and it arrived to destination. What's the issue here?
