Because you have used a negative indentation on the hanging indent, this is what is resulting in cutoff text in Outlook. If you need to see this text, AND it needs to sit left of the other content, then you need to set the other content further to the right. I don't see any tables in your template.

However, I think your workflow is dodgy. From your question it sounds like you are receiving an email in Outlook, then you open Word, create a new document from a template, type into that document, create a reply to the email, copy/paste from Word to the email reply, close the Word doc (probably without saving). This is way too many steps when Word appears to not be necessary.

Wouldn't it be better to stay in Outlook where the formatting doesn't rely on templates and styles aligning between Word and Outlook?
IMO, you should create the response template as a new email in Outlook, format it as you want to see it, then select that content and save it as a Quick Part in Outlook by going to Insert > Quick Parts > Save Selection to Quick Part Gallery.
Once this has been done, you can just hit reply to the email you receive and insert that content by either selecting it from the Insert > Quick Parts dropdown or by typing its name and pressing F3.

Quick parts saved this way get stored in the NormalEmail.dotm template in your templates directory. Knowing this allows you to copy that template to other machines if you have several librarians who all need the same functionality.
