I have happily used hotmail for years and had few problems. As one account gets busy(not just junk, but too many links etc), I have created new accounts. I have had 3 accounts for a while, check two of them daily and the other one weekly.
Since end of June I have noticed some messages from Shapeways have not got through. This roughly coincided with new computer arriving and Windows 10. Possibly a coincidence, but everything I tried with settings did not fix problem, so I set up another email account, just for Shapeways emails and messages and it seems to work fine.
I think there might still be another problem with messages not getting through on old account, which I still will use. If anyone has sent emails to me and not got a reply(if required), then this might be the reason, and suggest sending a message via forum.
This has not been a simple case of messages being treated as spam, as they have not gone in spam folder. I think it might be related to switching to Windows 10, as it did grab this email account for logon and I have had a couple of small problems. One reason I try to keep things separate and not linked as some seem to want us to to go.
