I didn't see any link which did the registry change automatically. I did it manually (and found it quite frightening to do so!).
I have no idea whether this is going to continue to work. It has only been a couple of hours so far. I'm waiting to see how it continues over the next day or so and/or whether anything else crops up, particularly as Clitheroe Kid says he/she has to change server address back and forth every day. I also wonder whether things will change when my home hub reallocates my 4-block (IMAP) IP address
I think you would be well advised to check the registry entries to see whether they ARE now the same as what Clitheroe Kid says in https://learn-attachment.microsoft.com/api/attachments/20b2fcb9-e29d-4e52-b9fb-1231c5f6968f?platform=QnA
Put your server settings and ports back to what they were in WLM. This MIGHT be the same as what Clitheroe Kid said -
imap-mail.outlook.com
smtp-mail.outlook.com
Outgoing smtp port 587
Incoming IMAP port 993
and check the SSL boxes for both
- but I obviously can't be sure these are correct as I'm not on MSN mail.
Assuming your registry IS now correct as per the filestore image referred to in paragraph 3 of this post and your WLM server settings are back to what they used to be when it last worked, then close WLM and reopen and see whether it now works.
Hopefully Clitheroe Kid will revert later with further advice.
Good luck
