Manage your own personal held messages queue

You can manage emails that have been held as suspected spam, or held for other reasons, without leaving Outlook. With the Mimecast Outlook add-in, you can allow and block messages, block senders and mark them as safe.

In New Outlook, you can find the Mimecast add-in under the ‘More Apps’ button in your Home tab.
