Pinning and unpinning the panel
The iManage Work panel closes whenever you select an email other than the email that you selected to open the panel. To ensure that the panel remains open for the current session, that is, until you restart Microsoft Outlook, select Pin Tab 
in the upper-right corner of the panel. The icon changes to Unpin Tab 
and you can select it to unpin the panel. Pinning of the panel is valid only for the current Outlook session and you need to pin the panel again after Outlook restarts.
NOTE: The iManage Work panel is displayed only when one email is selected. Due to Outlook limitations, multi-select is not supported. When more than one email is selected, the panel closes even when it is pinned and is displayed again when only one email is selected.
