If group messages sent to your email address are returned to Yahoo! Groups as undeliverable ("bouncing"), your Yahoo! Groups account may be temporarily disabled.

Messages can be returned for several reasons:

• Your mailbox may be full -- try deleting messages from your Inbox.
• Your ISP may have a backlog of email to process -- contact your ISP.
• Your ISP may be blocking email from Yahoo! Groups -- contact your ISP.

In many cases, Yahoo! Groups can automatically reactivate your account once the delivery problem is solved. However, this process can sometimes take a few days. To immediately reactivate your account:

1. Visit your My Groups page.
2. Look for a bounce alert near the top of the page.
3. Click Go to My Email Preferences.
4. Click Unbounce next to the bouncing email address.
5. This immediately sends an email to your mailbox. If it’s no longer bouncing, you’ll receive that email. Click on the link in the email.

Note: Reactivating your account will NOT immediately restore email delivery. The change in your status still needs to be propagated to all your groups. Usually, this happens within hours, but there may be occasions (particularly if you’re in a group with more than 75 members) when it may take a day or more.
