I have just started using Yahoo webmail. When I activate the “Move” drop-down list it only includes about half my folders. Is this normal? If so, it is a rather useless feature.
I resolved the problem by reverting to the Classic version of Yahoo Mail - by following your instructions. FYI I was accessing the webmail using Safari and Firefox browsers with Mac OS 10.7.2. Perhaps the new Mail has not been tested with this configuration.
But - thanks for your help.
