A user was unable to connect to their Microsoft Exchange using Outlook Anywhere – as soon as he enabled cached exchange mode and restarted Microsoft Outlook 2010 it hung with the "Looking For credential tiles" message. For this user, Outlook 2010 works fine without cached mode enabled. It's just when cached mode is enabled that it brings up this message.
This message is caused by a third party authentication service. For this particular user, it was Lenovo Veriface, but other biometric authentication devices can return similar messages.
You'll need to disable the service or uninstall it.
This user uninstalled Veriface from the Start menu, All Programs menu – browsing to the Lenovo folder then right clicking on Veriface and choosing Open file location to get to the uninstall application. You should be able to uninstall it from Control Panel, Programs and Features, but I since I don't have a Lenovo laptop, I can't confirm
its listed there.
If you'd rather disable the service, type Services in the Start menu's search dialog and select Services when it comes up. Location the biometric service then right click on it and choose Properties. Stop the service then set the Start up type to disabled.
