Dear Experts,
I'm having issue with our OU based collection where I moved some PC out of collection, move in some new PC, the new PCs are updated in SCCM console. However, the old removed PCs are still there on the list. Please help to advise why this happened and how we can overcome it?
These problematic PCs, some were moved to another OU, some were not used anymore so they were deleted from AD directly.
