Ok so the title pretty much says it all.
We are offering a Hosted Exchange solution for our customer. Everything is working fine except for one customer complaining that he is receiving winmail.dat or winmail.txt attachments instead of the actual Word Excel or PowerPoint attachments he should be receiving, only when these messages come from a specific European senders, that is using Lotus Notes.
I know that usually the problem is coming from Outlook senders to other mail clients, but this is not the first they inform me of this but I can't find anything on the matter so far.
Has anyone ever gotten and solved this problem? If not, does anyone have any idea regarding this?
I had solved this problem a few months ago, by upgrading Outlook to SP2 and then uninstalling it using the Service Pack removing tool of Microsoft. It seems that only the latest SP1 version could work but not the SP2.
The problem is that now nothing is working at all.
Thank you for your help,
