I’ve been looking around all over for a way to configure multiple exchange accounts to work with Outlook 2010. The official word is that “Outlook 2010” isn’t supported by BPOS yet, and it’s left at that. One of the fortunate things about working for a company like InterKnowlogy is that we often have the liberty to experiment with and use non-standard or un-supported technology on a regular basis. Here’s the exact steps to setup Outlook 2010 on Windows 7.

Note that you will no longer be using the BPOS client to start outlook, and these instructions are for Outlook 2010 on Windows 7 only.

1. Login to Outlook Web Access.
2. Click on Options in the top right hand corner.
