Are suspicious emails, safer to read offline?

Are suspicious mails that may contain hidden javascript code or tracking cookies etc or something to get information, safer to read offline? By offline i mean, they will be transfered into some windows mail client like outlook express, while i am online. And then, after i disconnect from internet, i read those mails on the mail client like outlook express. Will that be just safer or completely safe?

I'm not really an expert, but I'm never comfortable downloading my e-mails. But, there shouldn't be much difference between reading e-mails online or offline if you have a decent e-mail provider, which actively scans your incoming e-mails for viruses, and if you have a decent anti-virus solution. Having an up to date browser can also help in stopping malicious javascript from being executed. What I can say is that in both cases of reading e-mails offline, or online, it is never completely safe. Suspicious e-mails can carry much more than just tracking cookies or malicious javascripts. A more definitive answer can probably be given by someone from the Malware team. I hope that helps, Nahumi
