I have Windows 8.1 on my PC. I have a windows phone Lumia 635. I have a linked inbox on the phone. E-mail messages appear on my phone but disappear from the PC.

As a test, I forwarded a message from the phone to the same account (@msn.com). the message briefly appeared in the inbox on the PC and then disappeared as if deleted. The messages do not then appear in any other folder.

The problem only seems to be with the PC; messages remain visible (for a time, at least) on my phone and they can also be seen when accessing my e-mail account from a laptop. However, my PC is my main device and I want to be able to use it for most e-mail communication.
