Outlook 2016 introduced a great deal of new functionality and included in the new features is the ability to quickly compose a reply or forward an email right from your inbox, without opening the full compose window.
Unfortunately, NXPowerLite does not work with this quick reply/forward feature, meaning that your email attachments will not get optimized.
There is however both a manual and automatic work-around to ensure attachments get optimized by NXPowerLite.
1. [Manual] Pop open each email reply or forward to use the full Outlook 'Compose' window.
Click the ' Pop Out ' button and you will see the NXPowerLite button in the full 'Compose' window
2. Ensure that the NXPowerLite button is enabled.
In the compose a new email window or when you pop out a reply or forwarded email, the NXPowerLite button has to be enabled. The button has two states (Enabled/Disabled) and will remain in the set state for future emails until the state is changed. For example, if you disable NXPowerLite, it will disable NXPowerLite for all new emails.
3. [Automatic] Configure Outlook to always open the compose Windows for all replies and forwarded emails
Open Outlook
Click on the File menu option
Then click options on the left hand side
In the Replies and forwards section, enable Open replies and forwards in a new window
