Below you will find most common reasons why email cannot be sent, replied to, or forwarded.
Switch "Rich Text" to "Plain Text"
The inability to send, reply, or forward emails could be from a program that was installed on your computer that is now preventing the Yahoo MailRich Text toolbar from launching properly. Try switching from "Rich Text" compose mode to "Plain Text" as a work around:
- Sign in to your account.
- Click the New button to start a new email.
- To the far right of the "Subject" line click the Plain Text link.
- Compose and send your email.
To make "Plain Text" your default when replying or forwarding, do this:
- Sign in to your Yahoo Mail account.
- Click Options, then select More Options from the pull down arrow in the upper right corner of your Mail page.
- Select "General" from the list of options on the left side of the page.
- Check the box between to; When replying & forwarding and Mark original message with > (plain text only).
- Click the "Save Changes" button in the upper left corner.
