Microsoft Office has two bit versions available for Microsoft Outlook, (32-bit and 64-bit).  This is important to determine which version of the RMail App for Outlook you should download & install.

• If you have Outlook 2007 then you have 32-bit Outlook.  Outlook 2007 only comes in a 32-bit package.
  
  
• If you have Outlook 2010, 2013 or 2016, you should check which version you have prior to the download & installation of the RMail App for Outlook.
  
  
• From the Inbox, follow these steps to determine which bit version you have installed:
  
  
  1. In the Outlook inbox, press “File”.
     
     
  2. If you see in that column, “Help”, then you have Outlook 2010. Click “Help” and you can see whether you have 32-bit or 64-bit Outlook after the version number.
     
     
• If you don’t see “Help”, click “Office Account“, then click the “About Microsoft Outlook” button and you will be able to see whether you have 32-bit or 64-bit Outlook after the version number:

Once you have determined which bit version you need, use one of the links below to download the correct version of RMail.

IMPORTANT NOTE:  The RMail App (11.1.1.0) for Outlook works on both 32-bit and 64-bit versions of Windows so the Windows bit version is not relevant.
