Not sure if this helps but I too had the issue you are describing. I was becoming very frustrated as well and assume it was the RedHorse Outlook Link. Well it was not! It appears for me to be the same as described by RedHorse Support above. I have a laptop as you do, I used a docking station at the office and another at home. Sounds similar to your setup.
I changed my login to make sure that I used the same DOMAIN / Profile from in office and at home. By having one profile, I believe its been a couple of months since I've seen any issue.
One thing I still notice is that if I am at home and the VPN is not connected, the RHOLink will complain about the drive not being available but it still moves forward and later it is NOT gone/shutdown.
My installation is stable and I now run an environment where RedHorse is the center of the "Contact/Business" world for me.
I run RH, Outlook, Apps.Google and the associated Outlook/Google sync back to my local Outlook.
My Droidx communicates fulltime with Google contacts (my contacts from Outlook - sourced in RH of course), mail and calendars (again sourced from RH via RHOlink). Meaning that I have essentially all the information I need on the phone as well as online as well as in RH. Finally, it seems like I never have to say "....darn, I dont have that with me....."
To put this in perspective, we are a RedHorse dealer - so we might be a bit biased, but RH is not our only represented solution but is one of the top solutions for our customer base. We have just gone to an environment where we will all run DroidX devices communicating as described. I know we'll have future input but we feel that RH as the base is a strong starting point.
That was a bit off topic but, the solution to your issue is probably the 1 account login from where ever you are on your laptop.
Maybe that "Yoda" found you and led you to the light!
