Cannot access IMAP server (or POP for that matter) for Sky Yahoo Mail on Outlook 365

[morgad1963]

I have had this problem for a while now on my desktop and laptop and have tried all the advisories including generating an app password.  Outlook working fine on my iphone. Tried deleting and re-adding the account and given I cannot even connect to the IMAP server I cannot recreate the account (outlook working fine for my MS outlook mail address). 

When I try to add the account into outllook I get a failure logging onto the incoming mail server (IMAP) and a send test email message failure with the following error messages: 

Log onto incoming mail server (IMAP): A secure connection to the server cannot be established.

Send test email message: Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.

I am at a bit of a loss to be honest. This issue just happened out of the blue, not sure if a windows / office update may have caused it, changes on the sky / yahoo end of things or something else. I am using Outlook 365 classic and not the new outlook 365 that I believe doesnt currently support IMAP 

Any assistance would be appreciated

What server settings are you using, if you are able to try manualling setting your email account up using these:

Select either "Other" or "Not Yahoo" then use these settings:

Incoming Mail (IMAP) Server

Server - imap.tools.sky.com
Port - 993
Requires SSL - Yes

Outgoing Mail (SMTP) Server

Server - smtp.tools.sky.com
Port - 465
Requires SSL - Yes
Requires authentication - Yes

You will then need to generate a 16 digit password and use that instead of your usual one, you can do that here:

Hi there thanks for your reply tried what you have suggested already including app password plus alternative MAPI ports too, hasn't helped still same issue I'm afraid

Try these settings, they work on Outlook 2021 for me.
