Those objects should be excluded by the default sync rules, have you made any changes to the scope filters and such? There's no point deleting them in O365 as they will just be resynced, you have to exclude them from the sync scope.

There's no way for me to know that, having zero information about your AD structure. But as I mentioned, those should be filtered out by the default rules, so check your configuration. Here's the filter used:
IIF(IsPresent([isCriticalSystemObject]) || IsPresent([sAMAccountName]) = False || [sAMAccountName] = "SUPPORT_388945a0" || Left([mailNickname], 14) = "SystemMailbox{" || Left([sAMAccountName], 4) = "AAD_" || (Left([mailNickname], 4) = "CAS_" && (InStr([mailNickname], "}") > 0)) || (Left([sAMAccountName], 4) = "CAS_" && (InStr([sAMAccountName], "}") > 0)) || Left([sAMAccountName], 5) = "MSOL_" || CBool(IIF(IsPresent([msExchRecipientTypeDetails]),BitAnd([msExchRecipientTypeDetails],&H21C07000) > 0,NULL)) || CBool(InStr(DNComponent(CRef([dn]),1),"\\0ACNF:")>0), True, NULL)
