When using outlook exp 6.0, I receive this message. I got a solution from one of the other threads. The solution was to zero the count, in the registry, which worked. However, after several days, the same message returns "To free up disk space OE can compact messages". If I go into the registry and set the value to zero, it's fine for a few days, but still returns. Any idea how to make this setting permanent, or is there another solution for this problem? Please help!!!
