SCCM 2111 - Ou based collection not deleting old records

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.

    Hi, @Eaven Huang

    Thank you for posting in Microsoft Q&A forum.

    May we know how do you moved some PC out of collection and move in some new PC? Do you mean remove some PC in the OU and move in some new PC?

    Ou data come from two places, ad discovery while the computer does not have the cm client installed and heartbeat discovery after that. Until the client see that it belongs to the ou, and run heartbeat discovery and collection is updated. They will show in the old ou.
