DoIhavetoworryaboutallthosenewSPOsites?
Teams handles most of the work…
• Teams ensures SPO site members/owners kept in sync with the
PC owners/members
→ Teams PC member/owner change to SPO= immediate
→ SPO member/owner changes reverted within 4 hours to Team PC settings
• Teams will also ensure the SPO site for the PC lives & dies with
the PC
→ PC deletion triggers SP site deletion
→ restoration of PC = restore of site
→ Teams triggers restoration of sites if deleted before PC
But SharePoint is still SharePoint…
• Management of explicit SPO permissions outside of SPO
member/owner groups is on you
• PC site collections are not visible in the SPO admin center but
are discoverable through PowerShell and APIs
