I have been running various Outlook versions for many years including the Outlook 2010 beta and never have had this problem. Now with the Home version of Office 2010 every third or fourth time I open Outlook it goes thru a lengthy data verification procedure. It can take a minute or longer to verify data before opening the program. I dropped the number of saved emails from 2,000 to less than 200 and it is still acting the same. How can I get this procedure to stop running on such a regular basis? I can close Outlook and re-open in 30 seconds later and have to go thru the verification again.....when nothing has changed in that 30 seconds. It is extremely aggravating. Any suggestions?
