Oops 503 and 717 errors

We’re working on resolving issues with IMAP that causes some users to see these errors when accessing their Gmail through the web. They may also experience delayed mail. This is caused by the IMAP client accessing a folder with a very large number of messages in it.
We suggest the following workarounds:
  • Ensure all IMAP folders you access have a limited number of messages in them by moving messages to other folders or archiving them. For best performance, we recommend limiting your folder to less than 20,000 messages.
    Note: Using the advanced IMAP setting to limit messages visible to IMAP will not help for the current issue.
  • Unsubscribe from large folders in your IMAP client, if your client supports this.
  • Typically, the ‘All Mail’ folder is the largest. The only way to limit its size is to delete your mail, which we don’t recommend. Disable access to the ‘All Mail’ label in your Gmail Settings in the ‘Labels’ tab. Uncheck the ‘Show in IMAP’ checkbox for ‘All Mail’ and any other large labels.
    Note: BlackBerry’s Enhanced Gmail Plug-In requires access to the ‘All Mail’ label. If you disable access and need continued access to your mail on your Blackberry device, you’ll need to switch to a regular IMAP setup. Follow the instructions for Google Apps Accounts here.
  • Revoke 3rd party access to your account for any websites that access your account through IMAP.
  • Disable IMAP in your Gmail Settings in the ‘Forwarding and POP/IMAP’ tab.

When you copy and paste text from Microsoft Word 2007 into Gmail, extra space may be added between lines. Here are three ways to avoid this problem:

  • Change Word's default style settings to the Word 2003 style.
  • Change your paragraph format settings in Word to add a 10pt space after each line.

Scrollbars disappear when using Gmail in a small browser window

IMAP clients timeout or crash when downloading very large folders
