Emails sent through Microsoft Hosted Exchange arrive as winmail.dat attachments..

Hi there, I've started experiencing this problem only recently; I have a hosted pop3 account on an icewarp merak server. I have 3 separate contacts that both utilize the microsoft hosted exchange / bpos service. whenever they send me an email through their outlook 2010 clients or microsoft webmail, I see a blank email with a winmail.dat attachment.

If they send the same email to my gmail account, it arrives fine.

how can I prevent this from happening and start viewing their emails properly?

Using withe the winmail.dat attachments, it means  your email client is not able to read their email file format ie rich text or html.

Your email client for your pop account may only be able to read text formatted emails.

Are you using a email client software to read emails for your POP account? Which client software?If so, change it to read formats in html or rich text. Sounds like you cannot read html emails.

send test message using text format to confirm.

Microsoft's explanation:

Other than users' (including you) making changes could search up TNEF (or winmail.dat) Viewers to deal with examining them directly as they come in.

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

pretty sure that the icewarp merak mail server has a capability called TNEF parsing (a TNEF parser) but it's like an API into the server's handling of those winmail.dat attachments for programmers/coders to avail make use of

can you confirm what the resolution was as I have the same issue here with a Plesk server getting email from BPOS.
