Hi Mike,
I haven't seen that error before. I did a search and it appears that "not a legal OleAuth date" is an error that refers to the date not being between 1-January-4713 BC to 31-December-9999 AD. From what I've read its when can happen when converting a date value. I'm not sure why it would be occurring here, since the dates would be coming from Outlook and would be obviously with the range. Have you made sure Windows and Outlook are completely up-to-date?
If this is still occurring, please call our support line at 1-888-925-6238 x2 so we can investigate with you and get to the bottom of this.
