Question about Outlook Express

Hi there

Windows Live Mail has stopped receiving emails from one particular sender, for no reason that I can see. I haven't blocked the sender's address. There are no email rules set up. I have been receiving email from this sender for several years, but as of last week their emails are not appearing, and they are not going in the junk folder.

Any help much appreciated.

I have been trying for days to move my WLM storage folders and their email contents to Outlook 2016. I have hundreds of stored folders, subfolders and sub-subfolders.

There appear to be two distinct problems:

1) If I try to export more than one level of folders at a time (for example a folder and one or more of it's subfolders) I get a message that I don't have enough disk space or the emails are corrupted. Neither of these are true - I have plenty of disk space (yes, I did run Disk Cleanup too) and the emails are not corrupted.

2) I can export either a single folder, or several folders which are on the same level. The exporting process appears to be working fine:  I can see the correct number of emails being processed and then I'm told that the export was successful. These new folders appear in Outlook 2016 however they are completely empty. I haven't yet been able to move a single stored email.

I have four emails accounts in Outlook 2016 which are set up fine and the online emails are all in place. I am currently using Windows 7. This is the process I've been trying to follow: https://support.office.com/en-us/article/Import-email-messages-from-Windows-Live-Mail-B7775E37-F072-4AF0-AF22-F03841A150AD. I recently installed the 32-bit version of Office 2016. I did a repair on Windows Essentials but it didn't make any difference.
