Recent problem downloading mail to Outlook

[belle55]

In the past couple of days I've been unable to download emails to MS Outlook although they work on my iphone and on the webmail.  I've received error messages and tried to change my email settings but POP3 is greyed out and I cannot change it to IMAP.  Please advise

I have moved your post to the email board.

Have a look at these threads. There was a problem with the whole of Yahoo yesterday.

It is not possible to change from POP3 to IMAP in Outlook on the fly. The account has to be deleted and re-created to do so.
