To answer your questions:

32-bit vs 64-bit:
Microsoft officially recommends using the 32-bit versions even on 64-bit systems for compatibility with 3rd party add-ons.  You did NOT make a mistake or do anything bad, don't worry!  The 64-bit versions are only advantageous in rare circumstances where you are working with VERY VERY large spreadsheets or databases, etc.  99.9% of the time, you're fine using the 32-bit version.  The 32-bit version also uses slightly fewer resources, so that's an upside :-)

Cached Exchange Mode & older messages
If you set a cache period of 3 months, your offline storage table (OST file) will synchronize the most recent 3 months worth of email.  If you sort by date and scroll all the way down to the oldest message, you'll see a link that says "Click here for more messages from Microsoft Exchange".  If you click that link, Outlook will load older messages that are not already cached in the OST.  You can also use Outlook Webmail via your Office 365 portal and see all your messages there if you don't want to download them to your computer using Outlook on the desktop.

Hope that helps!
