If the emails to be loaded into Google Drive as PDFs are in a web-based email system such as Gmail or Yahoo Mail, you can load them to Google Drive as PDFs using Cloud HQ. Of course you only need to load those emails which relate to the case (not, for example, personal emails about something unrelated). Cloud HQ allows you to select emails from a particular email folder (label) or folders and it may well be that the emails you want to load as PDFs are in a separate folder or folders. If not then you may need to create a new email folder and copy historical emails to that folder, before using Cloud HQ.
When you are ready to use Cloud HQ, go to www.cloudhq.net and register/log on. Once logged on, tap Go To Dashboard, select Sync, choose Single User Set Up. Then select Back up one cloud to another cloud and the Sync Wizard panel should be displayed. Select one-way sync and press the square for the email system you have, such as Gmail, Yahoo mail, etc. and follow the prompts to log on to your email system and the further prompts to select the subset of emails to be loaded. Then press the Google Drive square, press Add Google Drive and follow the log-on prompts and select the Google Drive folder into which the emails should be loaded. Chose the appropriate synchonisation options as shown above and tap the Start Sync button.
When Cloud HQ has created PDF copies of the emails, Cloud HQ will send a confirmatory email to you saying e.g. The initial data transfer between your Gmail and your Google Drive has finished successfully. The sync between these two accounts is running now. Continuously and indefinitely. If you are using Cloud HQ to continually create PDF copies of new emails as you send or receive them then you do not need to do anything more when you receive this message. If, however, are using Cloud HQ just to make one-off copies of historical emails, you can, now that that process is complete, log on to Cloud HQ and press the Delete Sync Pair button.
Note 1. If the emails are not accessible from a web-based email system (so that you cannot use Cloud HQ) but you have them in Outlook on your computer, an alternative method of creating PDF copies is explained here.
Note 2. The PDFs produced by CloudHQ will have names like this 2017-03-23T13-57 [John Smith] My suggestions so that they will have the name of the sender and the subject, but not the recipient. Most legal cases are about matters concerning a small number of people and, in this case, not having the recipient name in the PDF name is not a problem. If, however, there are a large number of people sending out and receiving emails it is helpful to include the name of the recipient by generating PDFs in this format 2017-03-23T13-57 Email John Smith to Peter Jones CloudHQ cannot do this by itself, but you can use CloudHQ to create EML files (tick Export messages into EML format, and untick Export messages into PDF format in the panel shown above) and then use PSTViewer to create PDF copies from the EML files. PSTViewer allows you to create PDFs in 2017-03-23T13-57 Email John Smith to Peter Jones format.
