Changing date from Outlook

Hi-

I'm trying to set up Smartsheet to track follow up on a large number of small projects.  Using the smartsheet for outlook app with the web-based version of outlook (my desktop is 2010), I am not able to update a column with a date from outlook.

I am trying to set up a system to alert me if I haven't received an update on a task.  I tried to create a "last contact" date with conditional formatting, so when I get an email I can attach it to the task and update the "last contact" date.  If i just connect the email it works, but if try to change the "last contact" date it doesn't show up.

Next tried to create a "modified date", which sort of works if I change the status (smartsheet for outlook will change status).

These aren't critical dates, I just want to be able to use the card view as a dashboard to see who I need to be checking in with.

Any thoughts on why it won't let me update the date, or another way to set up a similar system?

Thanks,

Mike
