I have a relatively new client who uses all Mac products in their environment. One of the higher-ups uses a pretty beefy iMac (Intel Core i5, 8GB RAM, 1TB HDD). His Outlook 2011 is responding very slow (eg: takes 10-15 seconds for new email message window to appear, characters take about 5-10 to appear after typing, etc.). His e-mail identity is setup as follows: 6 active e-mail accounts, 8 sets of folders in the On My Computer. I have backed up and rebuilt his identity, made sure all e-mail account settings were correct and all On My Computer folders were accessible, but still the slowness persists. Short of starting with a new identity, is there anything else I can try or am missing?
