Specific Instructions for Outlook IMAP

Sent Items

Our SMTP Servers automatically place sent emails in the Sent folder. However, if you send an email with Outlook, it also saves another copy in your Sent folder there.
To avoid duplicates in the Sent folder, change the following settings:
In Outlook 2007:

• From the Tools menu, select Options and then Preferences
• Choose Email Options and uncheck Save Copies of messages in Sent Items folder.

In Outlook 2010:

• Select your Zoho account from the Account Settings menu and click Change
• Choose More Settings, click Sent Items and select, Do not save copies of sent items.

Downloading full messages

By default, Outlook downloads just the Sender, Subject, and the Date Information (headers) when syncing email. It downloads the full message only when you click on that email. You can change this behavior by changing the Send/ Receive Settings.
